I think it makes sense to install users unconditionally.
Mostly because not installing them is a minor optimization of the resulting
rootfs image and I see no good way to handle it.

If necessary, perhaps listing .users to be included in the project .mk
file may be an option, the same way it is done with .run files.

That's a valid point, but I think buildroot already uses its own
initscript format, namely its sysv(-style) initscripts.

They are supplied with buildroot, they are non-standard, and they are
nearly useless outside of buildroot.

So I see it a choice between different formats for buildroot-specific
service description, and the one currently in use does not look like
a good data storage format at all.
