I’ve done this before and it allows you to get some of the feeling of “being watched” with none of the privacy or security problems.
Also sometimes it’s neat to see the crazy process of building something, particularly if there is ui or visual design tools involved.
Also, I do think there is a whole additional level of understanding needed to practice or “work out” in front of an audience. There is some flourish to it, even if you are mostly doing your thing, you may have more round corners than you might otherwise.
It is definitely a different experience.
