Question on best practises of versioning/releasing Adaptive forms

We are about to scale of adaptive forms delivery and expecting a lot of forms ready to be deployed into Production. My questions are around how to source control these forms, i was thinking since these are content we should not be keeping them in GIT (?).

I know versioning is offered as a on demand feature, would that be enough ? we will have multiple teams delivering different forms, wanted to build a robust/effective process. Any recommendations or advises will be of great help.
