Sure, I can post a v2 with better wording in the description to make it clear.

Yes, it was a rhetorical question. I understand the motivation of that commit and agree with it. That's why $SUBJECT doesn't change the current behaviour, and the EFI runtime services will still be disabled by default for RT.
It's just to allow a way to enable for RT users that may want to. But having a separate boolean symbol also allow non RT users to disable it by default.
