Can someone explain the point of shooting reversal then making
reversal prints or an interneg then positive print, unless one wants
to mix colour and black and white? I remember a Kodak film path poster
from years ago, in which reversal-interneg-print was a not-recommended
option, and if you go that route it must be more expensive than
straight neg-pos, surely?

Most of the filmmakers, I know, in the UK anyway, shoot neg then print
to pos. I do that myself and have never had problems. Why is it
dangerous? It shouldn't be if the lab are half competent.

In London, at least for now, one can get good prints done in colour
and black and white neg-pos, and I've also had very good results from
Niagara in Toronto, notwithstanding it's a dry gate printer there.
