After posting about this over on the FreePBX forums (see https://community.freepbx.org/t/migrating-freepbx-with-fop2-to-new-hardware/96580/6), not only is FOP2 still around but what I have seen and now experienced, support is pretty active via Telegram (and that includes Nicholas).
Apparently all their website information is out of date. To get support you'll have to get on Telegram and go to:

There are English speakers there so you can ask questions in English if you need to.
So the answer to my question is a big YES
