Buildout can't pull default branch if named "main"

mr.developer: No such branch 'master'
mr.developer: Updated 'bda.plone.wallee' with git.

Configuring the branch=main within buildout "solves" the problem

As main is much more used nowadays, is there a chance to make it the default or have an option to define the default branch name?
