Hi. This commit broke our integration with tsserver. Now the commands are 'phantom' and we cannot reference them in our code. For example we use it here:
https://github.com/JetBrains/intellij-plugins/blob/master/AngularJS/src/ngLanguageService/angular-session.ts#L46

We use own abstraction under tsserver (in fact tsserverlibrary.js) in IDEA / WebStorm / other jetbrains products so a lot of users will be affected.

Is it expected breaking change?
