I believe we decided that it'd be okay to use one or two codes defined
like "internal error", "corrupted data", etc for all the elogs that are
not-supposed-to-happen conditions. What error codes are really for is
distinguishing different kinds of user mistakes, and so that's where
you need specificness.

Please read some of the archived discussions about this. All the points
you mention have been brought up before.
