OK, but why? The temperature would be stable so the resistorsand reference
diode wouldn’t drift.
Is the TL 431 not

No, the temperature is not stable, not even close.
Given that the TL431 is quite good
Are you sure? Perry was proposing to use a TL431 to
make an oven, using its famous temperature sensitivity,
and inside the oven would be another TL431 that acted
as a voltage reference.
Every oven I have ever seen that is temperature controlled
has a part that is quite good at measuring
