Agreed that this could be better.

Someting like this seems reasonable to me, assuming there's a patch to
review and we are confident it doesn't break anything.

Are you wanting to change the default of
  /usr/pkgsrc/category/pkg/work
to be
  /usr/pkgsrc/category/pkg/work-PKGNAME
as well?

Using WRKOBJDIR, I think you are proposing to change
  $WRKOBJDIR/cat/pkg
to
  $WRKOBJDIR/cat/$PKGNAME

I think that could cause trouble because we allow multiple PKGPATH
entries to build the same PKGNAME.

If you mean something that swaps lang-foo to langNN-foo as a
pseudo-PKGPATH for WRKDIR purposes, I can't immediately see any issues,
but it's more complicted.  But so far that seems best to me.

  $WRKOBJDIR/cat/$PKGPATH-$PKGNAME

would work, but will often be overly verbose.
