Yes.  A new MT "date" response has been added.

Yes, we do care about scripts/clients that parse CVS output, which is
why we avoid such changes in the stable releases (1.11.x).

We also prefer development to be able to move forward without being
overly encumbered by such considerations, which is what the feature
(1.12.x) series of releases is for.  When 1.12.x becomes stable, its
output format and client/server protocol will be frozen as well and a
new feature branch created.

I wouldn't have a problem with a change like this.  A patch with
sanity.sh test cases would probably get lots of attention.

That depends what you mean by serious.  I, for one, would love to see
it happen.  Useful development goes on in both trees.  Unfortunately,
I don't have the time to make a concerted effort at the moment and I
haven't seen many patch submissions (I will be getting to the edit -c
patch shortly).  Without funding or more patch submissions, the merge
probably won't be happening quickly.
