As I stated above, VFR-on-top operations are conducted on IFR flight plans
and the purpose of this section is to explain the services to be provided
or
not provided by ATC to VFR-on-top pilots.

"VFR-on-top" is still an IFR operation. That's not what Peter is talking
about.

Basically, your belief that a pilot flying on an instrument flight plan is
immune from the scenario posted in the original message is simply wrong.
All it takes is a pilot on an instrument flight plan (satisfying the 6000'
cruise altitude), and another pilot flying VFR (not "VFR-on-top"...just
plain old VFR) climbing on the airway as described by the original poster.
