"1. What choices would you make to design for an ideal electrical environment? For a non-ideal environment? "
From the aspect of the electronics alone; a properly wired three prong outlet."2. Is it possible to design equipment that functions optimally in both ideal and non-ideal environments? Is equipment designed like this limited in performance relative to equipment designed for an ideal environment?
From the aspect of the electronics alone; a properly wired three prong outlet.
Hope that answers your question, and as you implied in your first post; the theory and applications where done at least thirty years ago.

The above link is a good start; Bill Whitlock recommended that a switch from the signal ground to the chassis/earth ground at the return of the power supply for each unit would give manufacturers and users the options they need.

what, precisely, means "properly wired"?
Please see the electrical code, but in general; the hot and neutral are not crooswired and the earth ground goes back to main panel, connected to preferably an incoming water pipe. Since some don't have an incoming water pipe they can use a properly connected stake in the earth, or in the case of some larger apartment the steel frame of the building which can and in many cases is tied to earth ground.
ATTENTION! Please consult an electrician for what is applicable in your residence, as I have outlined some general case scenarios and do not attempt to do any of the above on your own. As for you Jim: consult with an electrician or electrical contracter on what is required.
