Is this an actual problem?  Do you know of applications that make this
assumption?  If so, is this unfixable?

I'm not aware of any actual problem.

I’m not too hopeful about this variant, but I’m rather ignorant about
venvs.  My main concern is about whether it will still be possible for
users to create venvs from a subset of their installed packages when we
generate a pyvenv.cfg by default.

venvs never contain a "subset of installed packages". They either include all system site-packages or none of them.

But as I've already written, generating a pyvenv.cfg for this case will not work as we need it.
