Personally I like top posting... :-)
I think automatic tuning PID controllers have improved in the last 30
years, the software has become friendlier, but there are still things
that need manual tuning, or at least some type of manual intervention.
I'm sure you can get a PID controller that

When you only have a hammer every problem looks like a nail. I think

I imagine a setup where three 500 watt halogen bulbs in series
(giving maybe 250 watts worth of heat, and a lifetime that will outlive
me) are nestled in an aluminum plate.
Why not:
I think you are talking about cascaded PID loops. Where there is an
outer loop that drives an inner loop.
The classic example is a vat, vessel, or reactor that is used to combine
or mix ingredients which has a steam jacket around it.
Here is a description:

30 years ago I used something like this for controlling a muffle furnace
to 600 C +- a degree or so. Self tuning pid loop.
I would hope the
