Can you point exactly in the documentation where would you want some 
clarification ?

Installation is a complicated topic. The PROJ project has no control over how 
PROJ is packaged and installed, and doing the "check at installation" means a 
different technical reality for Debian, Fedora, MS4W, OSGeo4W, conda, etc.
That said I took note of Chris Crook's idea about a script to help, as a post-
installation means (could potentially be run automatically by whatever 
installation process is done)
