This is what we do at work.

Unless there is some major database or library or language version change in a feature branch, once that branch is tested and QA’d, the M.O. becomes “merge any feature branches that we’re ready to put live into master and release”.

Long-lived branches are a mess, and rebase flow is crushed by them.

If you can fit this kind of simple Git workflow into your development workflow, I recommend it.
