I always was annoyed by the fact that it is not possible to disable the built-in bangs. Especially for services/websites I never plan to use and just cause conflicts on my end. Quoting the bang does allow searching for the term literally, but this also gets annoying real quick. I voice my support for an option to disable the built-in bangs. I think this is more of an accessibility concern than a preference since the list changes over time in unexpected ways, and users can't control it on their end.
(Besides the fact that I prefer a colon (:) for this instead instead of an exclamation mark (!), but thats a different issue I'm solving with a PHP script on my end.)
