Agree 99%. I would not hesitate to power up a set from the 60's on
AFTER a good visual unless it were a very special set. BUT my
teacher job kicked in.
Since bringing up a modern set with a variac is MUST KNOW stuff
to trouble shoot hoz / hv / ps problems its a good exercise to
try it & see whats normal. So it may be a waste of time but it is
well spent learning time.

I found a Motorola from 1965 and was advised here that using a variac on it was not necessary. Sure enough it came up without a problem.

I think once you get into 50's ea sets with older style capacitors is when a variac becomes necessary.
