It’s really just a suggestion to turn off some extensions. Haven’t bothered to figure out what triggers Safari to do that, but you can still run uBlock Origin on Safari 12 and it seems to work fine.

I made an extremely simple extension using the new model around 2months - before I try migrating an older "actually useful" extension. But theres just no way its possible to migrate.
Apple doesn't care about browser extensions now, it seems they want everyone to move to the new model, so they can collect revenue on sales on ad blockers.
