  Revert "tentatively remove workarounds for `https://github.com/malthe/chameleon/issues/323`"

This reverts commit 5f492756bbf97a1514a4e47c62709d949bc96ba1.

At least for the moment, `chameleon` is not yet ready to drop the work around.
In addition, our test suite is not sufficiently complete to verify the safety
of all `chameleon` features without the work around in place.

  Log Message:
  -----------
  clearly state in the comments related to `chameleon` work arounds that those might go away with ``chameleon > 3.8.0``;
add a not to the Zope Book that ``chameleon`` implements `attrs` and `default` in a special way and that their value should not be changed
