// TODO: Insert interesting usage for derived types. Maybe we should change out
//       interesting usage approach for types, and instead find a list of "uninteresting" usages.
//       Rather, what I think we should do is this
//
//      t -> interesting
//      f > uninteresting
//      fileid 0
//      row 5
//      column 7
//      this could all be packed into 64 bits
//      "usages": { "t@0:5:7" }
//
//    interesting: 1 bit   (2)
//    file:        29 bits (536,870,912)
//    line:        20 bits (1,048,576)
//    column:      14 bits (16,384)
//
//  When inserting a new usage, default to interesting, but if already present
//  don't flip it to uninteresting.
//
//  When importing we remap file ids.
