Offhand, we want people to move away from series and towards 'base' as the preferred syntax from 3.x onward. 2.9 won't add support for Noble, so there's at least a question as to whether we should add support for 'noble' as a string, or whether we use this as the forcing function to move people over to base='24.04' instead.

(Note that is separate from the Juju bug about having a noble base for the charm to live in)

In juju/juju we are considering Noble to be the final OS that we will allow Juju to understand as a series. From here, --series will not recognise later codenames.

I feel it makes sense to replicate this in pylibjuju
