Very interesting. I wonder if this a result of some "swiss cheesee" effect due to constraints around UEFI and NVRAM themselves, when updating EFI variables.
NVRAM must maintain atomicity of memory transactions for power failures. Its whole purpose is to store data when you turn your computer off. As a result, when deleteing an EFI variable, you can't manage the individual bytes - you have to delete a whole entry (which can be rather large - based on the EFI specification and the code used for edk2, e.g. https://github.com/tianocore/edk2/blob/83a86f465ccb1a792f5c5...). Deleting these entries might become a problem when you start running against memory constraints and what slots in memory are actually available; hence a possible fragmentation issue.
Additionally, I appreciated how short and specific this blog post was. I enjoy the style of post of someone encountering a problem and solving it.

Project mention: Intel Announces Arc B-Series "Battlemage" Discrete Graphics with Linux Support | news.ycombinator.com | 2024-12-03
If the firmware is open source, perhaps it could be retrofitted. For amd64 motherboards that do not have native UEFI support, retrofits are possible through this:

Project mention: Show HN: I Made an Open-Source Laptop from Scratch | news.ycombinator.com | 2025-01-22
came here to shit on this project, that there was no way it was open source down to the ME, like a raptor or framework computer. absolutely required IMO to be considered open source.
i didn't find any firwmware in the repo (didn't look exhaustively) but I did find that the SoC this is based on is supported by https://github.com/edk2-porting/edk2-rk3588 .
AFAICT the azoteq trackpad has proprietary firmware, so if that's true then i won't call this laptop open source. but from a practical perspective, i am much less worried about that then the boot path.
love the keyboard, wish i could test drive it!
very impressive!
