Well ... that seems to me to not really be "getting around this (problem)". After all, the idea of idling quietly means just that ... idling in the mid-hundreds of RPM for maximum quietness... not rev'ing somewhere above 1000 RPM. The high-idle approach raises the noise back up above the quietness of a truly idling Sprinter's small diesel engine.
As many know, the Ford V10 RV engine can of course "idle" for hours at a low 550-650 RPM, which makes outside engine noise ultra-low (lower then small portable Honda inverter generators at their idle speed). Inside an idling V10 motorhome, the (our) engine cannot be heard or felt. Very nice and un-obtrusive.
The problem is only a problem to those delivery companies. The drivers could not care less that their vans idle a bit higher. Especially since they aren't even in the van when the motor is at high idle in the first place.
To everyone else, it is a non-issue. Well, except to those whose lives are enriched by attempting to make it a problem....
