I don't agree. For me the idea (at the origin) was to avoid to get stuck 
with the map being rendered.
If you have a very slow wms and want to precisely adjust the extent of 
the canvas, you would first disable rendering, move the map as you want 
to and then start rendering.

It used to make a lot of sense before MTR.

As previously written, I think it will become totally obsolete once 
rendering of every type of sources can be properly stopped.
