It sounds to me that people are split on whether or not SCM should include things like issues and wikis directly, or let others solve it.

Considering this is the largest point between fossil and git that I can see, maybe we should just make it so git has the capability to expose an extension API for plugging additional capabilities like this in.

Then we could probably all use git and just be happy. You could theoretically use fossil's issues and wikis with git.
