Your point is a bit moot because removing bios support will actually allow the maintainer to stop maintaining the bios parts regardless of the fact some other old things are kept.

While actually not removing bios support won't allow you to get rid of the aformentionned MS techs such as fat support.

Having said that I think this is a wee bit early.

You made a factual mistake: MBR/BIOS based boot does not depend on a specific filesystem, nor does it depend on a specific executable file format except for the boot sector. You can safely remove FAT support from your kernel config, except when you need it for EFI.

I never said that.

I said removing bios support allows you to remove anything that provides bios support and that choosing to not remove it won't allow you to get rid of the EFI dependencies so it is a moot point to talk about old techs used by EFI.

"Full of faeces from cows" is and remains vulgar no matter how it's spelled.

There's nothing "vulgar" whatsoever about cow dung. It is an eco-friendly, renewable material and commonly used for many sacred rituals in India.

The GP literally used it as a weird coded insult to UEFI (for whatever reason), India doesn't really enter this discussion.
