Yes, in this case I could have looked in there, but that file is overwritten with every ./configure, right? That means there's no guarantee that what's listed there is for a given Emacs build. I think that configuration options should be tied to, and viewable through, Emacs regardless of the value it's set to. If report-emacs-bugs needs to know when to hide the options, then perhaps a new variable could be introduced for that purpose.
