For "?"

• No point in breaking existing URls and software to make something which looks different from other URls.
• Translation to make the gopher command line is trivial.
• It is useful to be able to tell, for a *generic* URL, that it is a set of query parameters applied to an underlying object, and deduce the URL of the underlying object.
• The fact that the semanics and internal syntax of the search string is not defined in the URL spec and takes make forms does not affect these points.
