Shouldn't it belong to grub-common?

I'd expect:


(and, yes, I use the last 3 boot loaders on my USB Debian system, since
I sometimes boot it from a PC, sometimes from a 32bit Mac, and
sometimes from a 64bit Mac).

Easy: if there's only one, use it; if there are several and the user
didn't specify which to use, signal an error.

Signalling an error sounds very safe to me.

No need to rename it.

Assuming update-grub runs all the versions of update-grub by default,
I'd expect grub-set-default to do the same.

It's probably not the same for efi-ia32 and efi-amd64, either.  Yes,
that calls for a renaming.

No, I don't think it likes it.  But renaming isn't such a big deal and
grub-common can hold the shared files.
