I've worked at companies with 20 employees, and companies with 100,000 employees, and not once have I ever been asked to participate in pair programming. It would have been immensely useful in college, but VS Code already has a built-in tool that would do the job... and VS Code works on operating systems that I actually use.
Who is using this? What do you use it for? I don't mean to be facetious, I have just never been exposed to pair programming in a professional space.
