Rephrasing to...:

       Note: the fact that the value syntax for the "realm" parameter is
       restricted to quoted-string was a bad design choice not to be
       repeated for new parameters.

The issue is that - depending on the API - after you have run a generic 
parser you simply might not have that kind of information.

It's comparable to require an XML attribute to be quoted with single 
quotes, and to disallow double quotes. It can be made to work by 
customizing the parser, but why would you want to?
