Actually, it's not -- depending on what your idle is, of course. Let's say you're idling down at 700 RPM with a
hot idle at 10 psi in a brand spankin' new stroker FE, say a SCAT with the Chevy journals, and clearances approaching .003", and a nice HV
oil pump. 10psi is nothing to even blink at, provided the pressure comes up right off idle. The original 427FE didn't even flicker the light until 6psi - and the service bulletin's recommendation for when that happened was to just raise the customer's idle a bit. The need for a higher psi at hot idle is all in your head.
