If the rule is you can have the flag in, then you're not "abusing" anything.
FYI, I already plan telling my partners on first tee to leave pin in unless I ask. I play solo golf a lot, and rarely have the pin out. Ram those short ones in against the stick
I think this has probably been harder to legislate for than you would imagine.
In reality they are making the rule to speed things up a bit and include fewer things you can be penalised for, but the unintended consequence is that it will have an impact on play and scores..
Hence why I would not be surprised if we see a move back, at least for elite play and use a form of local rules to let clubs make their own decisions rather than have separate rule books.
