> I didn't go into the fact that there are some ports depending on mercurial and I wanted to give those a target to depend on that included the python version. But with 24, 25 being on the way out and most ports defaulting to 27 it probably will be an issue that goes away.

I have about half of this work already done in my own local repo.
Would you like me to finish this up and create a ticket(s)?

Matt Mackall has been pretty clear that he isn't interested in doing
the conversion to python 3:

So, for a the foreseeable future mercurial and friends will need to be py2X.

The forest extension is mostly dead, having been replaced with subrepos:

so I would recommend removing it. Same with hgsvn (replaced_by hgsubversion).
