Mike: Concern for floors etc is certainly valid and reasonable. But I place the termination point of the extension as being within sight above that. It's that safety issue that gnaws away at me. Discharging just above a floor drain or into a pan makes more sense than onto a floor but that would be more of best practice than a requirement.

In any event, it's not front burner stuff and not worth loosing respect for the varying opinions here.
