Do we have a guideline on which functions we polyfill, and which we don't?

PHP 8.4 has more new functions, and and the likelihood of functions like mb_*trim functions being useful enough to polyfill is as good as the new array_* functions.

I'm not objecting this ticket in particular, just wanted to put my two cents forward that we probably should follow a guideline (of which I don't know if exists) so we can maintain the polyfills properly.
