[QGIS-Developer] Proj 7 auto grid download

Hi Nyall,

> - Take it another step further, and just immediately trigger the

I would be in favor of this option

Isn't that potentially a quite large amount of data? Most QGIS users 
that I know mainly work in one country or region and only need one 
gridshift file. Of course there are exceptions.
