It has been worth the abstraction in my organization with many teams. Thinking 1000+ engineers, at minimum. It helps to abstract as necessary for new teammates that want to simply add a new endpoint yet follow all the legal, security, and data enforcement rules.

Better than no magic abstractions imo. In our large monorepo, LSP feedback can often be so slow that I can’t even rely on it to be productive. I just intuit and pattern match, and these magical abstractions do help. If I get stuck, then I’ll wade into the docs and code myself, and then ask the owning team if I need more help.
