Thank you. You most likely are right. 

Although a feature like that would be nice (disabling the possibility of editing a layer that is not visible on the screen).

Depending on the layer modes of the layers above, a layer down the stack can participate to the visible output. And even in the case of all layers in Normal mode, Gimp would have to check the opacity of all the pixels on all the layers to be able to tell, a bit  heavy to compute a flag for the UI.
