These classes appear to be distinguished (section 2.2) in that %-encoding is essentially mandatory for gen-delims when building a URI (so, to make a path component with '/' or '?' in it requires %-encoding) but whether to %-encode is scheme-specific for sub-delims. I can't find anything requiring %-encoding of '+' in http URLs.

As discussed in the reference Leif provided, the content type
application/x-www-form-urlencoded uses the plus sign, so from that one
can conclude that a query string should use that as well.

Yeah, that's what I thought.

No, it's not, and I agree with Scott that might require some
additional language.
