When you are supporting a single file system and a  single TPM
configuration, etc... it is much simpler to stack more stuff in the
bootloader. But this is not the situation we have on Linux where we
have a dozen different filesystems and multiple different encryption
and authentication schemes, you are comparing apples and oranges here.

What's wrong to mimic things that work well ? Fedora should be about
progress and "first" and looking at what works well and do it.

Simo.
