Thankyou. This was extremely helpful.

One further question. Do you know of any legitimate, non-error uses of heavily backtracking regexes that cannot be better expressed using less stack hungry varients?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
