The way I look at it is this......

It’s a race car. It doesn’t have to have the drivability of a Camry.
At the same time, having to do a bunch of fancy foot work with the brake and gas pedals isn’t acceptable to me either, or having it try and die after the burn out.

If it starts good, idles reasonably well in gear, doesn’t try and die after the burnout, and requires a minimal amount of two footing while driving around in the pits...... in my mind, for that application....... it’s fine.

When it was a race car with a rowdy cam, I’d never leave my car idling in gear for any length of time.
I’d click it into neutral and let it bounce happily along at 11-1200.

Only during the times when it had pretty mild cams in it did I ever leave it idling in gear at stoplights, etc.
