I'm excited to see this migration happen, mostly because it signals to us (https://tangled.org) that large projects are willing to switch! We're working pretty hard to get Tangled out of alpha—we want it to be the place for free software communities.
Also recently wrote about our vision and commitment to indies and communities (and never enterprise!): https://anirudh.fi/future
Aside: Bluesky PDSes are configured to let you upload up to 100MB per blob. Perhaps it might be worth exploring as a medium for hosting release artifacts? Maybe the web interface can merge multiple blobs as fragments of large release files exceeding 100MB (or 15MB for PDSes using the out-of-box config which seems to be the case for Tangled’s instance)
You can already do this for tags, but manually. Via CI, you’ll need to set an app password and use goat (https://tangled.org/oppi.li/goat) or similar.
