if no module requires queryable values, what happens if it's installed?

Heh, I wish I were that much of a genius ;) There wouldnt be any performance gain just by installing this module. It's only going to improve performance of modules that actually utilize this module as a dependency. There are only a couple so far but I suspect as more and more people notice this modules existance, we will see conversion to it increase. Maybe to the point of someday being a core replacement for the variables system.

I've actually planned on doing that but I dont know how I will do it yet. I've been looking for a method in CVS to see if there are any dependency checks that I could utilize but I havent found any yet. The next idea I had if there wasnt an option for that currently, was to actually make the option myself in the form of a module. I have the ability to download all the .info files from the CVS (actually any anonymous user can do that) so I do have all the info needed to do such a thing so it is something I will be doing for sure. I havent decided on just how to do it yet. It will probably be a link on my own personal website that shows a list of what modules use my stuff, very similar to the one that I have on there already that tracks what websites use my phpGoogleStoreLocator app (currently a non-drupal app that I am making a drupal module for). It's been a huge success (the website tracking) because my site has a decent google rank and when I link to other websites, it in turn gives them a boost in SEO, especially if the users website is in the same field as my own (php development). So people dont mind that I track stuff like that with my non-drupal apps. Whether or not people in the drupal community like the idea I dont know yet but we will soon find out because I plan on tracking who installs what and posting the links on my site just like I did for phpGoogleStoreLocator. Its also reassuring to me that my work isnt going to waste. Its good to see that 500 websites have installed something I made. Not to mention when my own clients look at it, it assures them that I do know a thing or two about what I'm doing or else 1000s of people wouldnt be using my things hehe. So long story short, yes this is actually a feature I plan to implement, and soon. Maybe even today lol.
