I wonder why...
The only guess is that the sensor is very IR-sensitive (maybe has
sensitivity into the deeper IR-range?), which creates
some privacy concerns (as it [presumably] was the case with some
military-surplus night-vision tools).
My experience with my IR K-5 was that it didn't go far into the long
wave IR. Occasionally with it, or my IR FZ20, if I used a bright IR
flash and someone was wearing IR opaque underwear under cotton, then you
could see the outline of the underwear fairly clearly, but it wasn't
often a problem.
Any ideas?

IMHO, this camera is named incorrectly:
If the cut filter is removed and the IR filter must be placed over the
LENS, then that means that the camera has been modified to become a
Full Spectrum camera and you can put ANY filter over the front to
limit the wavelength of light reaching the sensor. This means
narrowband astrophotography is possible with it (astrophotography that
is not affected by city skyglow or moonlight).
You are not going to BELIEVE the astrophotography that can be done
with this instrument. (In addition to the other possible uses of any
full spectrum camera.) Super move by Ricoh/Pentax.
