Terminal Support for Emoji
I'm on the VS Code team and maintain xterm.js which is what Hyper's frontend is based on. There are actually multiple developments happening in this area.
First, there's a contribution from the author of DomTerm which adds grapheme cluster support to xterm.js, which will correctly merge and size things like emoji that are called out in the post. This is currently based on Unicode 15. See https://github.com/xtermjs/xterm.js/pull/4519
Second, while Windows Terminal does seem to work with emoji sometimes, it doesn't all the time. I'm not 100% sure, but I think it may only work on Windows ptys, not in WSL for example. Last time I spoke with the team they said they're working on a rewrite which could lead to proper emoji support.

No-more-secrets: recreate the decryption effect seen in the 1992 movie Sneakers
Ooh, I lack the time to play with this, but I think someone could compile the lib to WebAssembly and tie it in to https://xtermjs.org/
Then you could have a web page with static DOM elements that do this effect!

Integrating the WebContainer API with Node.js
xterm is a JavaScript library that provides a web-based terminal emulator with ANSI escape sequences, Unicode characters, and other features. It is easy to use and customize, making it a popular choice for adding a terminal interface to web applications.

Compile emacs to wasm?
The simpler path would be starting the WASM port using Emacs character mode running alongside an in-browser terminal emulator such as XTerm.js.

Ratatui: Build rich terminal user interfaces
Same for me, I would be much more motivated if there was something like textual for Rust. Given the capability of terminal emulators now I think Rust is lacking behind in the TUI field. Just checkout what can be done with something like notcurses

Terminal emulators that break from the traditional rendering approach?
On the application side of rendering, see notcurses, it is at the leading edge: https://github.com/dankamongmen/notcurses

Io Uring
The broader world probably knows him best for the terminal handling library Notcurses[1] and a lot of telling terminal emulator authors to get their shit together.
I’ve had his grad-school project libtorque[2] (HotPar ’10), an event-handling and scheduling library, on my to-read list for years, but I can’t seem to figure out how it accomplishes the interesting things it does.

Are We Sixel Yet
In XTerm, this (rightly) makes no difference. In Foot and Contour however, you still end up a line resp. a screen below where you started, if now with the correct horizontal position.
So it seems to me like what you want should work by default, except it doesn’t.
It should be possible to instead just treat the whole thing as a graphical overlay (by computing or directly asking for the character cell size, as Kirill Panov rightly admonishes me is possible with XTWINOPS) without touching the cursor; that’s what the “sixel scrolling” setting (DECSDM) is supposed to do. Then you can just manually move the cursor forward however many positions after you’re done drawing.
Except apparently the DEC manual (the VT330/340 one above) and DEC hardware contradict each other as to which setting of DECSDM (set or reset) corresponds to which scrolling state (enabled or disabled), and XTerm has implemented it according to the manual not the VT3xx[1,2,3]—then most other emulators followed suit[4]—then XTerm switched to following the hardware[5,6] (unless you and that’s what I’m seeing on my machine right now. So now you need to check if you’re on XTerm ≥ 369 or not[7]. If I’m reading the Notcurses code right, other terminals have followed suit[8].
Again, ouch.
P.S. It seems DEC had an internal doc for how their terminals should operate (DEC STD 070) [9]. It does not document DECSDM at all.
