I agree.

Technically you can "say" 12 different "wrongs" with the error codes [1] (and one "no wrong").



Why not have an optional error message like the "additional debug data" in GOAWAY?



e.g.



  0                   1                   2                   3

  0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
