Unfortunately, yes.
Historically, has_version in pkg_postinst would return results based
upon the version that *was* installed. This feature was widely used to
display context-aware post-install messages, and there were examples of
it in the documentation. Portage then silently changed this behaviour,
without an EAPI bump and without changing the documentation, breaking
all those packages in the process. The resulting mess discouraged many
people from bothering with that kind of thing...
