You can see why I was a little frustrated with the import speed. FSE's big but it's not so big that it should take a week to convert. Dropping all of the tables except users/activities/objects and then all of the indexes except object.data->>'id' (that is, removing everything the import script doesn't need) shaved off almost half the database's size, though. (~500GB to 284GB.)

Anyway, I've gotta restart it in a little while, but this time it'll be resuming from where it left off rather than starting from zero again.
