Documentation missing for extensionKind = web

In joelspadin-garmin/vscode-private-extension-manager#26, we are trying to get an extension to run on web versions of VS Code. I see in https://github.com/microsoft/vscode/blob/master/src/vs/workbench/services/extensions/common/extensionsUtil.ts#L38-L41 I that the package manifest's extensionKind supports a value of "web", so we added that to the end of the array and the extension appears to work when installed from a .vsix. However, in the issue linked above it was reported that trying to install the extension from the marketplace in a LiveShare browser session gives an error: "Cannot install 'Private Extension Manager' because this extension is not a web extension."

https://code.visualstudio.com/api/references/extension-manifest#fields does not document "web" as a possible value for extensionKind. Is the documentation for web extensions missing or is this intentionally undocumented?

Yes, web kind is not officially supported yet.
