Something like this is great for the following use case (1) you have a Chromebook, and (2) your working directory is on a remote workstation.

You can always ssh in, use tmux or GNU screen, and use a terminal-based editor emacs or vi. But if you want to use a different editor, you're out of luck.

An alternative might be to get some kind of remote desktop going, but that only works well with good latency, since every keystroke and mouse movement is going over the network.

A web-based editor should be less chatty. True offline access doesn't matter for this use case; ssh wouldn't work anyway.

Also, keep in mind that some companies don't even allow you to put your working directory on your laptop. With a monorepo, downloading the company's entire codebase (or even just the parts you need to compile) is risky and impractical.
