Yes, and so what? The sensitivity of a microphone can be altered by
changing the preamp gain.
Whatever the sensitivity/gain combination, the ratio between distant
and close sounds doesn't change.
i suppose the most obvious example would be something like
a piezo, where there would actually need to be direct contact
with the element in order to produce a voltage.
You'd be wrong. Piezo microphones were quite popular in the 50's and
60's. they didn't require contact between the capsule and the person
who talked.

In this case, the nature of the transducer (dynamic, electret
or
condenser) does not make a difference. It's only the distance
that matters.
Putting the mic as close as possible to the source increases
the level
of desired sound, when parasitic sounds are identical, so it
increases
the Wanted-Signal-to-Unwanted-Signal ratio.

Dynamic microphones have an undeserved reputation for being
less
sensitive to ambiant sounds or feedback, when they only
attenuate high
frequencies. Actually most condenser mics have a better
directivity
control than dynamics.
