That requires more bytes than a 32-bit integer.

And this adds code in every module, but for non-external modules we already
have reassurance that their abi is consistent (users should never bypass
grub-install; if they do, it's likely going to break for them anyway).
I understand there's a minor benefit for programmers of external modules,
but both things are at the expense of extra size to kernel and core.img
modules. External modules will only provide non-essential functionality, so
it's not a problem they have to check the ABI IMHO.
