Pilots are routinely taken below the floor of Class B airspace when

This is what I've observed too. Pilots flying hi level do not bother
with low level charts nor class B charts. Only hi level charts and
sid/star charts. Not saying it is safe, legal or proper, just that
it's normal ops.

Sam, would it be true too for the 2500 AGL within 4 nm limitation too,
in your opinion?

Secondly, is there some atc requirement that if your destination is
the primary airport in a class B, then atc is required to keep you in
class B, and not vector you below?
