Default Running stereo through a single tube with dual triodes?

There are numerous amplifier designs where both left and right channels are going into a single dual triode tube (ie TubeLabs Simple SE). What is everyones take on cross talk between the two inputs espeically where there is high gain involve in the driver tube. Is anyone worried that one channel will be heard in the other? I've also seen finished amps where the purist would use two tubes (one for each channel) and only use half (one triode)of it. Is this a waste of power or is there something to be gained when going this route? Just wondering...

HJ Leak did this when they started building stereo amps, e.g. in the Stereo 20. The first stage of each channel was a shared ECC83. I doubt very much if cross-talk would be much of an issue.
