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.
