They always do this, hence my warning!

Yesno! In Germany it's called "Trittschallfilter", loosely translated
"footstep filter". If you use it during the recording, it could be
useful, since it does suppress consequences of unwanted noise, such as
a footstep or hum. A footstep noise for example could cause a peak > 0 dBFS,
something you can't fix, when the recording is done. However, to filter
unneeded frequencies for speech, that could contain unwanted noise, you
still can use the highpass filter when the recording is done. A common
value is <= 80 Hz, not > 80 Hz. Depending on the source you recorded,
<= 80 Hz already could remove wanted frequencies, too. For human speech
100 Hz might be ok.
