So what is the problem with making it Boot0001? That way at least the
variable name is consistent across the board ;).

Yeah :(. What we really need would be that "bootefi bootmgr" becomes
"efiboot". But that would be even more confusing ;).

So the whole rationale of why "bootefi" is the way it is today is that
it's trying to lean on the existing "bootm", "booti", "bootz" etc syntax
as much as it can. In other words, it's trying to fit into the U-Boot
ecosystem much rather than the existing edk2 one.

I would like to keep following that path going forward. Whenever there
is an option between "U-Boot like" and "edk2 like" I would always opt
for the "U-Boot like" user experience, because if they want edk2 they
may as well use edk2 ;).
