As a user, I certainly do not find it hostile.
In a "batteries included" edit a service like copilot that expose all data to a third party is a terrible anti-feature.
As for script-oriented plugins vs wasm - I see a tradeoff - and don't think neither are right or wrong.
Cross editor plugins via a common wasm api might be fun, but perhaps not very practical.
