Instead of meta-search, git needs meta repositories. I should be able to specify an alias which represents multiple repositories, not just URLs like it does now. This way I could upload to e.g. @myrepo and have it upload across github, gitlab, and other git based hosts. Sure it could be done pretty easily with shell scripts, but it would help the cause if it were built in to git. I'm a git novice so it may already have this feature, but if not it seems like it would help with this problem.
