I haven’t reached out for internally (and I’m not on a related team), the following is my own understanding.

The blog post was most likely this one: https://github.blog/2022-09-13-scaling-gits-garbage-collecti...

And I think it answers the product vision for it well (why it’s automatic):

> We have used this idea at GitHub with great success, and now treat garbage collection as a hands-off process from start to finish.

GitHub also provides these docs for what to do if there is sensitive data in your repo, which is quite involved and (given the huge amount of knowledge internally of both GitHub internals and git internals), I would trust their advice:

https://docs.github.com/en/authentication/keeping-your-accou...

You can also contact support or create/join a community discussion: https://github.com/orgs/community/discussions

If you feel strongly that a feature you need is missing, by adding your voice, you increase visibility of the request. I think GitHub does offer solutions to this problem though, including eventual GC automatically.
