OK, I’ll concede that, since I haven’t used Open Mode on a F2.
Last time I was using Open Mode was on the F1+, in it’s early days, and it needed you to provide your profiles. The only default profile they had was for the clear, and you had to figure out on your own how to tweak it for your own resin. Most resins in those days didn’t work with the standard profiles.
But even if that was the case (and the F2 uses normal profiles in Open Mode), and Open mode just disables a few features and unlock the ability to simply pour in some resin and go, then why the delay? It’s not like they have to do any special coding and tweaking for it.
I think the reality is FL wants to milk the resin cow for as long as they can, then maybe a year or so down the line, they might open it up.
