Codeberg was asking about this. The linked toot by a commenter points to :

They are minimal. They provide the data you probably care about and the data you need to comply with the original license in SQLite format.

Yes, forum platforms too (incl #nodebb of course).
I do get the (very vague) impression discourse is focusing on integrating well with masto to a good extent and so might not integrate too well with the other Reddit/forum platforms. If true, that might be a good enough reason to start with another base. OTOH, it’s a familiar platform to many devs so adapting it for stackoverflow like use could go well right?
