And FWIW when I've flown international 3-cabin F on OW partners (before I had any OW status) OWE boarded before paid F. Most of them turned right after boarding though, so it seemed like a fair trade-off.
On UA, 1K (equivalent of EXP) preboards before group 1 (F of group 1).
This is why I say they if you get your wish of separating F from group 1, F will most likely be after the other people currently in group 1, not before them.
