My initial confusion came from the fact that I thought BUILD_ALL_PYTHON_FLAVORS was the default behaviour, and therefore users could choose which version of python3 to install from the default FreeBSD package repo. If that was the case, but installing meld brought in python36 as a dependency, then that would be sub-optimal. But my assumption was wrong - BUILD_ALL_PYTHON_FLAVORS is not the default behaviour, and the only python3 package therefore provided by the default FreeBSD package repo is python36. End users cannot opt to use a different version of python3 without rebuilding their own packages. I realise this is a different point to yours, but it was the original reason for my question.
