Exactly.

Do late model sailplanes actually have a "factory" grounding point?

Am I correct to assume the best grounding point would be the heaviest
metal frame work closest to the instrument panel such as the control
yoke or the adjustable rudder pedal track?

So in the perfect world all things metal (especially long lengths
like push rods) and your negative instrument buss should be grounded
to a common ground point?

I don't know how many adhere to the "single grounding point"; however,
note that the point is for the instruments, not necessarily everything.
The other metal bits, which are not carrying signals, can be grounded
elsewhere, such as the near the battery. A powered sailplane will likely
also have an "engine" ground, so the starter currents, ignition system,
generator, etc. are kept from the instrument ground.
