So you mean that map canvas would be completely 'disabled'?
What if someone zooms to a layer / full extent / bookmark?

To me the current behaviour makes more sense - but personally I would
rather remove the 'Render' option completely.

I would be in favour of that - whether rendering is turned on or off -
but maybe others feel like that is a useful feature, so I wouldn't
remove that without wider discussion.
