But there it's really just about 4 major separators and the scheme prefix! (Dot, slash, question mark, hash mark.) – Mind that we're talking about users who are already able to read and parse sentences, including punctuations. There's no special skill set required, just a few bits of information. Users are able to parse post addresses and apply specific meaning and rules to the various parts. (Compared to URIs post adddresses are exceptionally messy und full of edge cases and exceptions.) Before mobile, users have been able to identify phone numbers by country, region, city and district. Where is the crucial difference? Isn't just because they are told it does 't matter and they won't understand anyway!
