I don't.

As I suggested, slots in the dynamic environment could be added for
ports with more specifically meaningful applications; e.g., there could
be a DEBUG-OUTPUT-PORT added.  But as it is the current input & output
ports are not specifically intended for random debugging output, or
I've seen them misused a great deal, and even if they were that would
be hardly reason enough for the havoc wrought on signature consistency
for them (not to mention an unclear name).
