How to update the list of extensions?

[payne911]

This is what we run in a StartupActivity:

    val manager = OurLspExtensionManager()
    for (ext in SUPPORTED_FILE_EXTENSIONS) {
      IntellijLanguageClient.addExtensionManager(ext, manager)
    }
    val serverDefinition = OurServerDefinition(SUPPORTED_FILE_EXTENSIONS_STRING, command, repoRoot)
    IntellijLanguageClient.addServerDefinition(serverDefinition)

After startup, we want to allow users to add or remove to that list of supported file extensions. From what I gather, we should:

1. Update the ServerDefinition and ExtensionManagers via methods provided by IntellijLanguageClient
2. Call EditorEventManagerBase.forEditor(editor).wrapper.restart()

But it seems like there is no way to remove an extension in the step 1. What is the recommended way to approach this problem?
