probably understand the issues, so nothing to worry about from point of
view of GRASS developer. While on MS Windows user can be in the same
situation as I'm with compiled GRASS with the difference that he or she is
installed standard version and thus is possibly very unexperienced.

I just wanted to point out that there is a significant difference thanks to
packaging (and packagers!). No historical reasons, this is how it is.
