I strongly disagree with that, sharing Binary files is fine with git as long as you share only the necessary ones, the only time where git really fails is when it comes to uploading heavy files like textures, HDRIs or music.
I am currently using GitLab for source control (for myself only) with a peak upload speed of 64KB/s and I can say that it never took me more than a minute to push anything to source control (although I don’t push textures, so these do have to be sent another way around but currently I only use starter content textures)
