updateRemoteUserUID has no effect

[cadojo]

When using this CLI, the container or remote user's UID and GID are not updated. This issue is documented in microsoft/vscode-remote-release#10030, but I think the core issue might be located here. I have an example repository up on GitHub. Steps to reproduce are below. Am I missing something in my configuration, or is this a bug?

git clone https://github.com/cadojo/devcontainer-uid-example
id
cd devcontainer-uid-example
devcontainer up --workspace-folder . --remove-existing-container --build-no-cache
devcontainer exec --workspace-folder . id

I see the following text on containers.dev... does this mean that on MacOS, or Windows, there is no way to sync the container user's UID and GID with the local user's?

On Linux, if containerUser or remoteUser is specified, the user’s UID/GID will be updated to match the local user’s UID/GID to avoid permission problems with bind mounts. Defaults to true.

This only applies on Linux. Windows doesn't have Unix-like UIDs/GIDs. On macOS you would get the UID/GID mapped by Docker Desktop, maybe you are using something else?
