So much for Kawasaki's recommendations (no prohibition listed for "friction modifiers" or "energy conserving" in the KLR250 Service Manual supplement, either).

The Clymer Generation 1 KLR650 manual contains the same italicized caveat regarding additives you imaged above, but I found no specific friction modifier/energy conserving oil-in-the-bottle cautions:

Regardless, thanks for sharing your most interesting research.

Oils containing "friction modifiers" or formulated with some "energy-conserving" association may indeed be detrimental to wet clutches; just didn't recall any Kawasaki advice to that effect.

Sorry about your clutch; if it failed as a result of running zinc-laden Mobil 1, this fact's worth a warning to KLR (and other wet-clutch motorcycle) riders.

Again, appreciate the references.
