Comment 17 for bug 1561019

Given the (no) feedback and the fact that this actually is not part of the virt cpu the old request is won't fix. Furthermore I spawned a task to remove the patches that did add it in the past.

TL;DR:
- intentionally not enabled/added upstream
- long gone with a very low amount of people missing it
- still (and in future) available as opt-in by changing the config as outlined in comment #15
- will remove (disfunctional) related delta on next merge
