We are planning a tag for every push for the landscape-server and client
charms, and bundles.  +1 on it being mentioned as a best practice (the same
type of thing as when you release a version of any other software!).
Though, I would recommend using the full charm store identifier eg:
'cs:~user/charm-3'.  Basically, the full standard out of the charm push
operation.

I also like the repo-info for traceability the other way around.  They
solve a similar problem but depending on where you are looking are both
useful.
