I do sometimes. If I go to a friend's house with a big-screen TV and stereo, I can connect my USB-C dock, plug in the hdmi cable, and control from a mouse or the phone. Nice big display with multiple windows. Same for when I stay at hotels. I believe you can still get phones that have an HDMI out that's not DeX, but then you just see a scrunched up mobile phone display on a big-screen TV and no multiple windows.
