The single bleeder resistor is an interesting point, if one fails and you have a thousand microfarads sitting at +180V for hours that could be an issue.
There's a time-limit constraint, I usually pick a value that's pretty high for the bleeder in this kind of supply - 68k at 180V is almost half a watt of power, but it's also over a minute for one RC time constant (1000µf), and still over 50V (which UL considers dangerous) at the minute mark.
At some point you need to factor in the idea that the tech isn't a complete idiot, and will check those big dangerous caps before getting his fingers in there.
