[Sway] Should I always create a dedicated stream branch for my module?

Hi all, I'm currently working on a module for sway. We basically just want to have a stream that always contains the latest version of sway (including all its dependencies), the same version that is also in rawhide (this stream should be named 'rolling' if I understand the guidelines correctly). In that case, is it better to just use the master branch of the package git, or should I create a dedicated stream branch nevertheless? Thanks, Till
