Unrep Sub: Say Something or Stay Mum?

Batting out of order is clearly an Appeal Play by rule. The umpire is not allowed to bring to the attention of either team when he/she sees an improper batter at the plate. But the unreported substitution situation does not have the same restriction to do nothing until appealed as far as I know. And not all unreported substitution violations would result in an out. So do we say nothing for any/all types, or just those that would create an out when properly discovered?

You make a good point.
But absent that guidance from ASA, and assuming that there is not one in place already; until such time that ASA provides us by rule, R/S, manual, or a specific directive from OKC, a procedure for handling this specific sitch, I'm handling it like a batting out of order sitch.
I'd rather err that way than the other. JMO.
