>be used by those teams who want to move as much as possible to AWS
By teams that have been mandated to move as much as possible to AWS by their company's senior leadership, because it simplified accounts/they negotiated a "great contract" etc.
Having been on both sides, it often makes a lot of sense. A lot of companies have surprises requirements in contacts, such as HIPPA or military/classified or whatnot. The cost of adding a new vendor can be astronomical compared to the cost of dealing with CodeCommit.
In truth, though, Amazon should have bought gitlab instead.
Funnily enough when my infra team talked to AWS solution architects about this topic, it seems they were very upfront: don't touch CodeCommit, AWS/Amazon teams mostly use GitLab internally. And we do have a partnership plus discounts conditional to minimum usage volumes.
Slight correction, the sales org uses GitLab, mainly to segregate any “code” they build for customers. Internal AWS/Amazon teams use an internal git-backed UI.
If AWS forced their teams to "dogfood", it would quickly morph into the Testuo blob monster from Akira -- there are too many products/services popping up too quickly, and the amount of time and knowledge lost to the constant changes would be catastrophic.
Dogfooding is for simpler companies. It's also bullshit and best for product managers and sales. Let tech work with what's best for their specific internal environment.
