Have you seen such a problems or is just an assumption? I've worked on a
few puppet implementations and changing puppet master manifests on the go
has never been an issue.
I might be misunderstanding your question, can you develop more around your
deployment process?

I've got to agree with JuanBrein, I've been using puppet since 0.24.5
and I don't remember ever seeing a problem like this. How are you
deploying your modules?
Even if you have a time consuming deploy process (i.e. not just a git
fetch and pull), and inconsistent state on disk is a valid concern,
