I have one project on GitHub that I use all the time as part of a script and only push changes when the python API breaks it. It is essentially “finished” and usually just needs a quick compile against the new python version whenever I upgrade the distro. I haven’t even had to touch for at least as long as GitHub required ssh keys so by all accounts this would be an abandoned project.
Now that I think about it — it is a python wrapper around a boost library and neither of those have made backwards incompatible changes in a long time which is quite suspicious.
