I cant remember the last time i had someone pass a URL on to me by word of mouth that included the path, even let alone a query. If they feel the need to be accurate they email the full URL from their bookmarks. I probably wouldnt remember the path part accurately anyway. By your logic and this experience, the conclusion would be that every URL should have a domain only representation for best user-friendliness. Have fun getting you sys admin to plug your CMS into the DNS server , if you have one.
Lets get practical.
I dont think most users care, it transparent to them most of the time. Thats a sweeping, and uninformed statement. Or at least ill-considered. Path based parameters are just as easy to implement as query based. More to the point there are many good reasons to use query components.
