GitHub are terrible at this, because you can't have levels other than Org and Repository. And many things (SSO, visibility rules, common configs) are on the org level.

Unfortunately often the cleaner option is to create a separate org, which is a pain to use (e.g. you log in to each separately, even if they share the same SSO, PATs have to be authorised on each one separately, etc).

In Gitlab, you would have had one instance or org for Mozilla, and a namespace for Firefox, another one for other stuff, etc.

There is an “Enterprise” level above the org, but that obviously needs an Enterprise account. It lets you manage some policies across multiple orgs, including membership.

But it still requires multiple orgs, and the UX is still poor.

It's like AWS accounts vs GCP projects. Yeah, there are ways around the organisational limitations, but the UX is still leaky.
