"open exhaust port"... is this legal? has it been used in competition and permitted by the inspectors?

I was wondering if Rule <R72> Part C in Paragraph 8.3.9 applies in any way to this question:

"valves must have a maximum ⅛” NPT port diameter, and a maximum Cv of 0.32"

I was trying to figure out the purpose/intent of this Rule, and whether leaving the exhaust port open (or using more than one solenoid to feed the input) violates the intent of the rule?
