Mark and protect local commits?

Hi there,

I have often wished that there were ways to

a) protect certain commits from leaving the local repository

b) mark commits that have already left the local repository

To be more specific:

a) Sometimes, I try out certain experimental features and want to make sure they don't accidentally end up out in the wild. If there were a flag to explicitly mark them "private", any non-local operation (push, pull, etc) on these commits could create an error message.

b) For history-rewriting operations, it is important to know which commits are out in the wild and which are not. In a "push"-setup working copy, git should be able to keep track of this. Any newly created commit would be marked as "unpublished" and the mark would be removed when the commit is pushed. Any history-rewriting would be prevented on published commits.

Has anyone else thought along these lines?

Greetings, Norbert
