don't think it supports branches

it's also tough when you have 1TB of data, over 1mm files and you might want to lock hundreds files in one go

I mean, Git LFS 'supports branches' in that the LFS content identifiers are checked into git as files and Git operated normally; LFS is just a way to replace those content identifiers with the actual content, and then vice-versa when you commit.

I think branching is the one thing that didn't get more complicated with LFS.
