I want the information that it conveys, and this seems like a workable way of providing it.  I don’t think a RST_STREAM code or GOAWAY data can replace this, because they will only occur after a timeout. The BLOCKED frame can be sent after a much shorter time (1 RTT?) or even immediately.

On second thought, “debugging” is probably more important, because correct implementations should never reach this state.
