Will there be any “backfilling” capabilities for this module (to calculate sentiment for pre-existing content)?

Yes, this should be reasonably easy to add (at least a rake task for it)

Looks quite good on my forum! Is there a way to fill in more of a backlog after installing the plugin (self-hosted)? I’d be interested in running the analysis on all the posts in the last quarter or so in the background.

We will write a proper backfill rake task for this in the coming weeks!
UPDATE: You can now run it with `rake ai:sentiment:backfill`
