I personally am a designer as well as a developer but you are assuming that a designer couldn't learn git? It's a bit of a struggle but to simply clone, branch and push said branch this is pretty easy. You could deal with the merges if you wished.

I currently work in a designer studio and I'll be introducing everyone to Git soon. But most designers I know have some programming knowledge (for implementing) and would be able to use Git :)
