I don't have the clout to convince everyone to just use the same system over their own, even though we could tie it in pretty well.
For example, notifications would be sent to the people who are subscribed to the project. They could then do triage with just a few additional lines of PHP. Even I could write the code for such a site - but you'd do better by having someone more skilled than I write it.
Kinda like Ubuntu is pushing Snaps, available for all the distros - and for any FOSS projects that want to sign up.
We can grab Ubuntu's bug-reporting software - unless there's something better.
Alas, I'm not important enough. Nobody is gonna listen to me.
