I think moving to GitHub makes total sense. Every other open-source math project I use regularly is on GH, and there are big network-effect benefits to being where everyone else is as others have already pointed out: easier for others to contribute, easier to get credit for contributions, easier cross references to issues up and downstream, etc. Given the range of projects that use GH, including those like numpy and scipy whose issue/PR counts are similar to the number Sage trac tickets, I'm sure any technical or workflow issues have already been overcome by others and the solutions are likely even documented. Given the open-source community's reliance on GH, any serious misbehavior on GH's part would result in a massive pushback and, if necessary, a concerted effort by a huge number of people to work out an alternative.
