instead of useless error messages like "instance not valid to be used as import", why not dump the entire instance's type signature?

in wasmtime

like, why do we need

      (export $error-e "error" (type (eq $error-t)))
      (type $stream-error-t (variant (case "last-operation-failed" (own $error-e)) (case "closed")))
      (export $stream-error "stream-error" (type (eq $stream-error-t)))

instead of, say,

      (type $stream-error (variant (case "last-operation-failed" (own $error-t)) (case "closed")))

why does the latter not work? why doesn't wasmtime tell us why it doesn't work?
