Thanks for reporting this missing feature, I agree with you that we should provide better experience for users installing PPA packages, including 'providing the PPA package changelogs'.
Regarding the concern about a clear distinction between PPA and official packages, Apt/Aptiude/Synaptic already list PPA packages candidates as 'unauthenticated', but it doesn't seem to be clear enough. This concern must be considered when solving this bug.
At the end, I really believe that full-feature installation and authentication of packages content/origin are orthogonal and address different issues. That said, I'm still with ScottK when he says that the latter should be sorted first.
