Thanks Andrew for setting up a vote. Seems like a good way to engage the developer community.
May I suggest the wording to be updated to this?
* Versioned branch, e.g. ’11.6’, changes every 3 months (current method)
* Static brach 'main', does not change (proposed method)
By default git has 'main' since a couple years back, so I would propose only it (not 'trunk').
