Modo SE is still using 701 feature set, with no word of it getting an update at any point. With the inability to take your high poly outside Modo to bake, scripts become even more important.
I believe compiled C++ plugins work for the moment (scripts and Python plugins don't) but they will be removed later. I'm trying to see if some plugins will be allowed to work - some kind of whitelist. Mostly for my vertex toolkit and some UV stuff I'm working on that's useful for games.
