You have to post that as idea/request, just like
webp file support was done. And if you read it you'll notice yourself if you're just talking about embedding HEIC pictures (then
phpBB will support that already unless you have height/width restrictions) or if you want attachment support (then it could even be irrelevant if internet browsers can display it or not - but
phpBB might still enforce width/height rules and whatnot).

Then you're also unfamiliar with all the other candidates from the past (J2K) and the present (AVIF).
