I just spent a good deal of time to add nightly builds to some of our projects, only to find out that they can’t even be used without additional setup by the users who use them.
This is very disappointing, but it does explain why GPR never took off (basically because it’s not public yet). I would consider having to add an access token to your repo a hack, and a very dangerous one because the potential of screwups is huge (eg. adding tokens with too many permissions).
Please increase the priority of this so GPR actually becomes usable for open source projects / packages.
