It's good to have a high-value resistor permanently connected

Yes, all power supplies should have them. I use series-connected filtering caps, because their working voltage is only 400v and my PS can output as much as 475v with no load. Because of this, I am forced to use a resistor across each cap to share the voltage evenly between them. I use 100k 3w across each cap. However, even if I had caps with high enough working voltage, so that I didn't have to use them in series, I would still have a high-value resistor permanently connected across each cap. It's just common sense, as far as I'm concerned, to get rid of the charge once you've switched off.
