Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

GPU synchronization in Godot 4.3 is getting a major upgrade
Pipelines (or in general terms PSOs) are the most problematic aspect of Vulkan / DX12 - much more than synchronization! Large parts of the gamedev industry seems to recognize all the performance issues with pipelines and therefore companies are experimenting with newer models like the VK_EXT_shader_object extension ("Vulkan without Pipelines": https://www.khronos.org/blog/you-can-use-vulkan-without-pipe...).
I've written a detailed comment about this before here (https://news.ycombinator.com/item?id=37843946#37845431) but for a much more comprehensive explanation by an engineer from Nintendo read the initial proposal for the VK_EXT_shader_object extension: https://github.com/KhronosGroup/Vulkan-Docs/blob/main/propos...).
There's also Casey Muratori's mail to the Vulkan advisory on 2015 that basically predicts this whole clusterfuck would happen: https://github.com/cmuratori/misc/blob/main/vulkan_dynamic_s...

The Clean Code Debacle and Rhetoric Tricks - Casey Muratori vs Mr "Uncle Bob" Martin
Casey and Uncle Bob did have a conversation about the architectural part of Clean Code - unfortunately it seems to have ended just as it was getting interesting. I did want to add some of my thoughts to your comment though.
I'll put the link to Casey and Uncle Bob's discussion about architecture here again. This discussion is specifically about maintainability. In it they both come up with a design for a device IO API, and argue its strengths in terms maintainability and extensibility.

Is it possible and realistic to learn independent of an API?
Sort of, I'd recommend a modern higher level API. I'm not sure what the current recommended ones are (probably bgfx), but assuming the wrapper is "low level enough", then the concepts you learn are still going to apply.

LWJGL = SFML vs Allegro vs SDL vs Ogre vs ???
There's kind of a lack of this for C++ in 3D, I think it's often due to the necessity of a secondary scripting language in game engines with C++, which isn't necessarily needed in Java or C#. SFML is like that (but also 2D), Godot is similar (but more geared towards 2D). Ogre3D is an actual engine like I mentioned earlier, not sure how easy it is to use. Cocos2d is higher level, but is also 2D only. I'm not fond of SDL, it feels like a windowing library with slow old school immediate mode stuff attached, so it ends up not being good at the rest of the tacked on things. SDL is popular as a windowing library, and it's why you see it used everywhere (but the most notable uses of it aren't using their drawing capabilities), I often see bgfx thrown around, and for you it might be a good choice, though I have no experience with it.

Is it a crazy idea to create a 3D operating system?
Another route could be using an abstraction over Vulkan (faster, more efficient, more difficult): bgfx, dawn, magma, or wgpu (Rust).
-
The update we all want but will never get
my guess for why renderdragon made performance worse is because old bedrock was built on bgfx which is a layer of abstraction ontop of a bunch of graphics apis which benefits the programmer because they can write the graphics code once and use it on a bunch of graphics apis (just like java! i heart cross compatibility)
now, java is actually quite a performant language and even if its not most of the performance bugs in mc are due to it being single threaded, inefficient chunk generation and optimizing, and it built ontop of opengl WHICH isn't much of a performance hit but its still ehh idk it doesn't matter that much (NOW SWITCHING THE GAME TO AN ENTIRELY DIFFERENT GRAPHICS API WOULD SUCK ASS TO DO (and vulkan is quite verbose :))) (AND also bgfx would probably be better due to it being an abstraction layer ontop of all the graphics apis so minecraft could target many depending on your platform (and also bedrock used to (or still does i dont know) use bgfx before they switched to just two (IF IM READING MC WIKI RIGHT BECAUSE IM NOT ENTIRELY SURE IF THEY USE BGFX STILL ?? SO THEY COULD STILL BE TARGETING MULTIPLE YET THEY JUST WROTE THEIR NEW SHIT BAD IDK))
