Good point. Yes that would screw up. I was thinking the lack of 
environment variables would indicate a launch from a terminal, but 
unless all terminal clients cleared all the Wayland environment 
variables this would not work. And I don't think it should be the 
terminal client's responsibility to know the entire current set of 
Wayland environment variables and remove them.

I think that is enough reason to give up on the environment variable idea.
