Maintainer here. I get the concern, but that has not been my experience.

I don't think of the mobile side as a way to keep working on your phone on top of your full working day, although I will admit it can be used that way.

It is more about being able to step away from the desk without losing access to the work. Let's say you spend 6 hours at your desk, what if you could spend 2 of those hours walking instead?

To me, it has been valuable for steering long running agents, brainstorming ideas or triaging PRs/issues while taking a walk.

Fun fact, Paseo means "stroll" in Spanish, which is where the name came from.
