A short time after "git stash" was added to Git there was proposal to
automatically use git stash to allow merging with "dirty tree",
i.e. with uncomitted changes. This idea was abandoned, if I remember
it correctly because a.) there were too many corner-cases b.) it
wasn't necessary in most cases.
With merging into branch with uncomitted changes your fairly well
understood 3-way merge (sometimes virtual 3-way merge in the case of
multiple common ancestors) would turn into 4-way merge. Even if you
can automate it somehow (I do wonder how Mercurial manages that),
there could be problem resolving conflicts, unless you happen to touch
different parts of file.

Please take into account the fact that when you were creating your
workflow to suit your situation you were "forced" to fit it to
Mercurial abilities and best practices. No wonder that it does not
fit Git-ish workflows.
What you use uncomitted changes for, I would use is a separate branch,
and keep it rebasing (something like using 'mq' in Mercurial).

What do you use anonymous branching for?
Note that with Git by default pushing "matching" branches, you can
create private local-only branches. The have to have _some_ name
(even if it is 'foo/temp'), but I think that it makes them perhaps
more work to create, but easier to use (to switch branches)... and for
single anonymous branch you can always use "detached HEAD".
