Your response to the first point appears to explain why Git largely replaced Subversion, but it is not clear that it applies to Mercurial.

I'm not saying it won't, just that transitory UI issues are unlikely to drive a mass exodus from one source control system to another.

To reference a reply of mine to your sibling comment[1], it would have been like going through a lot of trouble to move from Mercurial to Git some years ago just because Mercurial's terminal UI didn't use coloring.
