Can I refer you to "Valve Amplifiers" by Morgan Jones, page 354? He specifically mentions cathode damage when HT is applied to cold signal valves in audio amplifiers. Morgan Jones is an ex-BBC engineer and this book is considered to be the most complete guide to valve amplifier design. Admittedly, he doesn't condemn nor praise the standby switches used on valve guitar amplifiers.
You choose your information source as you see fit.
