That's why ideally you have someone in your team who is trusted by the platform team to do what needs to be done to unblock your main goals/tasks. The platform team of course can help (or hinder), but the ability to do your own stack helps uncouple problems, helps teams progress. Ideally there's an equilibrium. Some teams will inevitably be outliers, but the majority will benefit from the platform. There's always a degree of sharing/coordination/communication. After all the teams are part of the same company. (Eg. when it comes to data access, API stability, it's a must to coordinate. Though famously Amazon "simply" solved this by a companywide mandate, requiring everything to have an API, and there's probably some story about their stability too.) So, in any case the coupling should be loose. Basically an almost wait-free (but at least lock-free) algorithm.
