Yes please.  We already have text if we look at the history before 73e11f64a704; we only need to agree on recommending “uncommitted changes in a clone” (which is okay to share patches but not for not ideal for more than one person working on something), named branches (what was in the previous text, because it makes it easy to run hg diff -r default and such commands) or bookmarks (lightweight named branches that some people recommend; I’m not sure how they’re better, given that in the end we generate a patch and make a new commit).

I, for one, use both uncommitted-changes and named branches; the former is easiest, but the latter safer: if I screw up a merge in a clone where I use a named branch, I can revert and retry the merge, but if I screw up merging pulled changes with my uncommitted edits, I risk losing them.
