The point of WATCH_ON_BUCKET is to watch for all 3 fields of the bucket, so the fallthrough is intended.

Unrelated thing I just noticed, but the function says it returns bool but here it returns 2.
I am going to blame myself for not catching this when I probably changed the return type, but is the value of 2 important here?

See https://heap.space/search?project=PHP-7.0&project=PHP-7.1&full=&defs=&refs=phpdbg_check_watch_diff&path=&hist=&type= (seems to have been irrelevant from the beginning).

Yeah indeed it seems irrelevant, maybe it was intended at one point to be used to signal the bucket key has changed, but who knows.
