I like this policy if am a track organizer and facing several older cars on the track!
Aside from the fact that it is rare for most cars to leak coolant, there are two reasons for not implementing such a policy - one philosophical, one practical.
The philosophy behind drivers schools is that you can take any well-maintained car out onto the racetrack without any special preparation. As long as all the routine maintenance is up to date, and a few items (brake fluid and pads) get changed a bit more frequently than for street use, and nothing is loose or likely to fail, you can take the car out onto the track. This philosophy is abrogated with the requirement for two additional services specifically for the track event that would not otherwise be necessary - the first, to drain the coolant and replace it with water before the event, and the second after the event, to put coolant back into the car.
The practical consideration is that the need for these two additional services is a deterrent (and, from what I observed at the FCA meet, a fairly strong one) to participation in the event. There are quite a few owners who simply will not take their cars out onto the track if these additional services are required. So, from a marketing and budgetary point of view, such a policy could very well be detrimental to the event.

As for overheating, quite a few NSXs that are tracked have reported overheating as well
Absolutely not true. The simple fact is, the overwhelming majority of NSXs never overheat, even on the racetrack. Sure, there are a few exceptions - which is why we hear about them on NSXprime, because they
are so uncommon - but they are usually caused by improper maintenance or other problems not inherent in the car itself, such as the damage that Steven may have done to his radiator, the probable cause of his overheating problem as reported
here.

Homestead disallowed anti-freeze during the weekend running in conjunction with the Grand-Am Race series.
Race series (competition events) have a lot of rules that differ from those for street cars in HPDE events; fluid requirements are just one area and there are lots of others. This is the first time I've heard of this rule being used in an HPDE event.
