We'd like to be able to set a default branch without setting up triggers.

The main purpose would be to have all users default to a specific branch, so that inexperienced users don't have to manually select it. We realized this can be done through an after-mkworkspace trigger, but this would not solve the other issue (below).

For our use case, we do not have any files in /main so when looking at the repositories, it says the repository is empty which is not accurate. /main is empty, however we have other branches with data. This could be confusing for users trying to setup their workspace for the first time.
