OP,
I started the topic @pooya87 referenced above,  eventually mods for an unknown reason decided it is being off-topic: https://bitcointalk.org/index.php?topic=5169284.0 I wish yours not to end that way.

That said, it is more than obvious that github is the worst option to rely on for development if you get too addicted and dependent. It is an open question though, how much bitcoin ecosystem is addicted to github, and what is the cure?
