The main problem is the necessary regression testing needed to actually verify
that the regressions
a) are indeed fixed
b) don't introduce new failures.

And our current testing system is hardcoded to "master" and "develop"
branches. And can't test anything else, as it relies on the test runners
admins to set up which branch to test.

As soon as we get an up-to-date regression testing and reporting system, we
can use any branching scheme you can imagine. And a lot more probably.
That would mean using either Jenkins or BuildBot as a centralized server and
some dashboard reporting tool for visualisation.
But I don't know anyone with enough spare time to set up such a system without
being paid and working full time. Not to mention the hardware necessary for
