I wasn't planning to push it for 6.15, as we've discussed this change
for a long time already, I don't think there is any rush now, though
I agree it would have helped to have it earlier.

I already found another follow-up, removing support for the sancov
gcc plugin that is no longer needed, I'm sure there is more.
