I really like that idea, but it's a pity to limit it to channels.
Two scenarii I'd like to see covered are:

 1) Find the latest commit with all substitutes required by a given
    manifest.

 2) Find the latest commit with all substitutes required for updating a
    given profile.

This is in fact only one problem with two user interfaces.

Konrad.
