at least tangentially relevant).

Exactly. However, AIM 3-2-1d is somewhat disquieting...

"d.VFR requirements. It is the responsibility of the pilot to insure
that ATC clearance or radio communication requirements are met prior to
entry into class B, Class C, or Class D airspace. The pilot retains
this responsibility when receiving ATC radar advisories. (See 14 CFR
Part 91)"
