I don't see "more information" or "no way to see how credible a LP user is" as an argument against registering the connection between a bug and an upload to PPA. This is not about the sponsoring process, it's just that there's currently not a lot of integration between PPA and the rest of Launchpad.
A lot of work happens in PPAs, a lot of work happens in bzr branches. Having the connection between all of them gives a much better overview over what's happening.
