How to specify a default <start-point> for git branch

Is it possible in git to configure a default <start-point> for the git-branch command?

For some workflows it could be useful to define e.g. a remote-tracking branch as the default <start-point> for new branches. Then there would be a tracking configuration for each created branch and tools like ALM tools could easily determine the remote repository.

For EGit-/JGit-development there is a proposal in Gerrit to add a new config parameter workflow.defaultsourceref (http://egit.eclipse.org/r/#change,4168). I suggested to use workflow.branchstartpoint instead.

What do you think about such a property?
