Just curious, there seems to be an implicit assumption that proj4/5 and 
proj6 (or GDAL 2.4 and 2.5 for that matter) can't be installed side by 
side.  Why is that? Shouldn't they have different .so major versions?  
Then wouldn't applications that haven't been updated yet continue to 
function with the Proj/GDAL version they were built against?

I understand this is a little messy for awhile, but why would this 
fundamentally be any different than a distro packaging multiple OpenSSL 
versions or Qt versions to keep all the applications happy?
