So would you say that if one were in the pattern that it would imply
the same responsibilities of ATC as if I were on, say, flight
following?

As Gary points out, whether or not ATC is coordinating transit through other
airspace, you still need the clearance. Beyond that, since flight into the
Class B isn't necessary for operating at KBFI, there would be no need for
ATC to coordinate transit through the Class B, and thus you would have no
expectation that they would.
