Also worth mentioning GitCenter (here's a public proxy link https://zn.amorgan.xyz/1GitLiXB6t5r8vuU2zC6a8GYj9ME6HMQ4t/re...) which runs on top of ZeroNet as is already in use by a number of people. Notably ZeroNet's source code is also mirrored here.

It has issues/PRs and the like, and content can be deleted quite easily.

Supports SVN too apparently.
