Exactly this. Obviously nobodys going to buy a flagship IEM just for zoom calls but having the option of taking calls in between listening sessions on the phone or laptop is very helpful. Especially when Etys are not easy to take off/put on in the first place.It's incredibly convenient if you're switching modes from listening while working to having to hop into a meeting. I don't buy the argument that having an inline mic makes an appreciable audible difference.
As software architect, my day is swiss cheese - I get about 1 to 1.5 hours to program, then I'm in a meeting / helping someone out / giving a presentation... rinse repeat all day. I'm regularly popping out my KSE1200/Z1R and putting in my Airpods Pro. Sometimes I just don't bother to switch back and enjoy the AP as it's 'good enough' though a clear step down.
The Ety isolation though is very attractive when working out of noisier environments like cafes, and if it was equipped with a mic that did a decent job of filtering outside noise it would be dream.
