I am not sure to understand how this change the problem of having
sources which are not-synced with the channel.  Unless you want to
modify nixos-checkout to look for revision number of the build inputs
used by the channel before updating.

Another question is, how would this impact binary diff, because if you
have one channel which correspond to one revision, and not multiple
then you cannot do a binary diff, unless the channel contains n
revisions [ R - n .. R ].
