well that was… something

Some tab grouping extensions use it to hide tabs that are not in the currently displayed group.

Indeed - users that need accessable features should not rely on each piece of software they use to supply them. But even as a one-off feature, it is a good thing to have IMO, as it will certainly expose APIs and hooks in vscode for other accessibility software to utilize.

Also, open source, learning, and all that jazz.

You may not find a use for it, and neither do I in my workflow. But think about accessibility - it might enable some users to perform tasks the find physically difficult using just their voice.

Or, you can go get a beer or a [slice of] pizza, and call out to vscode from across the room to build your app or start a server or something.
