Impossible to tell if someone's AFK or using /gpose

[Mhaeric]

Wouldn't it be much more practical and useful to see the AFK symbol next to their name instead?

No, because for all intents and purposes they're afk whether they have the chair or camera icon displayed. It's even in the name of the setting: idling camera. And neither setting is necessarily accurate to what is actually their state. Someone can be afk but not have the icon, not be afk but watching the random camera images for whatever reason, actually afk with the afk icon, actually afk with the camera icon, etc. I.e. the game now has two afk icons, the only difference being potentially letting you know what their UI is doing while they're non responsive.
