IOW, as the signal frequency increases, the BSR becomes the dominant
component of the device's input impedance... Phew! Unless of course,
someone knows otherwise...
Emitter lead inductance?

Er, yes, but I'm only interested in the *internal* characteristics of
the device here, so even the bonding wires' inductance isn't an issue.
Thanks for giving me the chance to clarify, though.
