Twisted is a library you might want to use if you want to write non-blocking code. So you would care a great deal if this wasn't python 3 if you wanted to use python 3.
Mercurial is an application you use to version control your source. I'm not sure I understand why any python developer would care if Mercurial was written in python 2 as long as it worked. Maybe if someone was writing a Mercurial plugin or patching Mercurial they would care.
