Are those migrations still editable, out of curiosity? Oftentimes I'll want to have migrations add things that simply aren't possible with some ORMs (e.g. generated columns, which can't be schema'd in most ORMs).

The main thing holding me back from Prisma is precisely what you like about it - if the migrations are auto-generated and I can't edit them afterward, I won't be able to do what I need to.
