I agree wholeheartedly about it only taking a couple of minutes
for the TCXO to warm up.  However, I don't agree with leaving the
Power Supply on all the time just in case one might want to turn
on the radio and operate.  I would no sooner do that than leave
my car idling in the garage to be ready if I need to run out for
a loaf of bread or something.

The basic tenet at KG5U is to have nothing connected to a-c,
rotator, remote antenna switch, or antennas when the station is
not in use.

If your station experiences one lightning strike (as mine has),
you will be convinced that (1) leaving equipment connected, (2)
the need to be able to turn on the radio and not wait the 2
minutes for stabilization, and (3) the need to be able to scroll
through the dxpacket cluster postings for the past day or two is
not necessary, not that important, and definitely not in the best
interest and well-being of the station equipment when the
operator is away.   Here in the Houston area, thunderstorms can
develop out of the blue.

Besides, having to go through the agony of dealing with the
insurance company to get equipment repaired/replaced (all
repaired; none replaced--how do you like them apples?!!), should
be plenty of encouragement to protect your station.  Definitely,
not a fun experience.
