Comment(by jmr@…):

 I think the dist_subdir being py-xyz makes more sense than having every
 single python module in the same subdir.

 The post-destroot would presumably fail in such a case since there would
 be no files in the work dir. You don't actually need an extra variable;
 checking if $name != $subport is sufficient. I agree it's a little
 unwieldy, but still less so than defining the post-destroot block once for
 each python version.
