Because modules are loaded from disk, not memory.

This brings up a good possible solution. Daemons can be required to link
to the static nss libs, assuming I compile that into the -dev package.
This means the modules would be static in the binary, and this breakage
would not occur.

How about programs like this link with -lnss_compat? This would solve the
problem by not requiring a restart at all, and keeping atleast standard
name services working (maybe it needs -lnss_files -lnss_dns and -lnss_db,
but that can be debated if this is initially acceptable).
