To determine how useful something is it's important to look at the usecase. My usecase for interacting directly with the store is that I want to look at some specific store path, so I already know the hash from somewhere and can autocomplete on the first characters with much higher precision than first completing drv names, and then moving on to the right hash. You seem to have some other kind of use-case. What is it?
