Doesn't matter if you don't - a 10M resistor isn't going to do much.

If one of the leads to the xfmr comes loose, the tapping clamp slips etc.
not too likely but it can happen
If the cap is an mmc type there may be a residual charge on some of the caps
after you discharge it, while the net voltage over the string is zero - this
is the purpose of a discgharge R in series with each cap - of course it is
easier and simpler just to encase the mmc so you can't touch the individual
caps.
