Yes: "opt-in" and "opt-out" isn't correct in the AutoFu by policy.
Likely easy to flip to "opt-in" if the spiffy (and useless)
by-the-book AutoFu is ripped out.
The more general ROADMAP issue is
OPENMP or "free-threading" as a model?
OPENMP is so easy to do one misses that its all of RPM code
would need to be refactored to continue the pretense of "easy".
I suppose I should open up
How should RPM become multi-threaded?
Its silly that RPM can only use a single processor
and "package management" is accused of S-L-O-O-W
all the time.
