I build a fully-static zsh all the time and have never had a problem
with USERNAME not being set.  Is this platform-specific, or is the
"when they compiled statically" specific to dynamic-nss ?

I think the idea here is that multiple lookup methods may be compiled
in, and you can choose to use different subsets of them, so it may be
the case that HAVE_* is true while desiring to prefer some other way
if available vs. never use some other method even if it is available.

I can imagine this logic got confused somewhere along the way, or that
certain cases were missed.  I think Clint Adams still reads this list
and it looks like --disable-dynamic-nss was his patch, so maybe he can
speak to it more directly.
