No, I wasn't considering the /boot (minus /boot/EFI) partition at all.

Yes, that's what MS recommends, but MS notoriously under-specifies
various minimum requirements and has done for decades.
The Internet generally recommends 100-500MB. There are recommendations
for 1GB.
The points to consider are that nobody knows what /boot/efi might need
to contain in the future, in addition to the current files, and given
modern drive sizes, the odd GB here or there is a rounding error. If
you reach the point where 900MB less spare space is really becoming an
issue, it's time you moved to a bigger drive or added more LVM space.
