Well, it works, and the W3C recommendations are extremely general — only the use of ? and + are defined. So I think from the perspective of HTTP/HTML the = is optional. It’s use is obviously a common convention and many client & server libraries use it, but there doesn’t seem to be any reason you couldn’t define a service to work on some other scheme.
Anecdotally, I like to leave out the =blah part when I’m using the query string as a flag as in http://www.example.com?logout
