Is there actually a performance issue?

I've seen this claimed, but I have never seen any actual numbers. What
speeds up? By how much? is it actually measurable?

Maybe they've marched past me in this thread-from-hell. But I can't
recall having seen any (not now, not before).

That said, I think the more serious issue is that if Luto complains
about the capability-capturing code being completely broken, then
people need to take that *seriously*.
