Only if the infrastructure you target has no concepts of versions, and if it only has monolithic environments (which still holds true for much of the older infrastructure).

But if we just take the GitOps branches problem, they are indeed not handled, but that's because you generally configure your GitOps pipeline to only allow interaction from a specific ref, not any branch you might have lying around ;-) The SVN version would either be trunk-based deployments or revision-based, where you have to tell your reconciler which revision you want.
