The current behavior is, in fact, based on Stefan's remark that

  There's no point trying to add support for some properties but not all:
  adding support for all properties is likely to be easier because it'd
  rely on (re)using the existing display code.

in that thread.

The changes are from 2013 so the binaries you have should include them.

If you can give a practical example where the present code fails to do
what you want, feel free to reopen the bug.

Thanks, martin
