We had something similar to this in a previous job. It was a large organisation and each team owned their own components, they had merge access etc. If another team wanted to make a change they'd submit a pull request and the owning team would review it. That owning team would impose their own process and tooling on top of the standard stuff that was org wide. The big difference I suppose is that the team were the ones doing the majority of the work rather than purely gatekeeping. It did work very well on the whole though, especially as that team would then be responsible it in production.
