I think it has been established only that a problem occurs in P::RD
where #18533 has been applied that doesn't occur where it has been
removed.

It hasn't been established yet precisely what is going wrong, but it
seems likely based on available evidence that #18533 was either wrong
or insufficient. In particular, given that the symptom is a hard loop
in intuit_start, it seems unlikely that P::RD is to blame. I'll be
looking to discover more detail as soon as a tuit presents itself.
