There is at least one relatively uncommon app where slow warmup would be disastrous: where both B+ and negative bias rectifiers are tubes, esp if B+ rectifier is DH. I've seen this primarily in really old high high power stuff like transmitters and PA booster amps. One notable high quality audio amp employing 5Y3s in the bias circuit was the Mac MI200.

So, while the caveat regarding slow warmup may seem excessively CYA, it's warranted IMO.
