Charged capacitors and inrush current in an appliance
You'd have to do long-term testing to find out.  You won't save any money if you skimp a few cents on resistors, but then have a rush of warranty claims in a few months time because the semiconductors keep blowing.
This is a safety-related component.  Touching a charged capacitor while standing on a step latter to fault-find a bit of kit (which probably has a blown semiconductor), and touching a capacitor charged to 300V DC could be nasty.  When measuring the remaining voltage, are you allowing for the resistance of the voltmeter?
