Is there a seamless solution for submitting plugins to wordpress.org SVN and GitHub? [duplicate]

The wordpress plugin repo does not have any API as far as I can tell for push and pull hooks from a 3rd party service like github.

Right now the solutions are hacky at best and require you to use git as a middle man (on your computer) and also deal with SVN’s use of tags/trunk/branch which git doesn’t like very much.

It’s not very fun or seemless, more along the lines of “can I actually do this”, at least for the moment.
