I do accept that languages can be opinionated and programmers feel like priests sometimes... but if enough new evidence mounts up then yes, it should get challenged and re-discussed.
I mean, we are talking about core team members discussing a not that trivial source breaking change for Sets and Dictionaries with dropping sequence conformance: https://forums.swift.org/t/on-the-elementsequal-problem-or-pitch-set-and-dictionary-should-not-be-sequences/12227?u=panajev
Opinionated does not mean "logic and explanations are not necessary these are rules set in stone never to be argued about again, deal with it or get lost". If it becomes an excuse for it then we would have a problem and I do not think we are there ;).
