> (At least in theory, we'd have to make sure the prompting message
doesn't vanish due to other output when building in parallel though. But
I think in practice this is very unlikely.)
Yes, I hope that a follow-up ticket will do a proper solution, which
prompts early (or just bails out and requires an extra flag), rather than
prompting in the middle of a parallel build.
My simple solution just restores (except for cosmetics) the status quo
before #20640, #20708 broke the prompting.
