I should also mention that you can probably workaround the issue by
adding the -novshift switch to your gdalwarp command line:

Hi,
This is indeed https://github.com/OSGeo/gdal/issues/6839 which has
been fixed in GDAL 3.6.1.

I think I've gotten this solved for my purposes now, but I'm
reporting it here in case anyone else might run across issues using
gdal in a conda environment. If I make a conda environment containing:
python
pdal=2.4.2
gdal
(which ends up with gdal version 3.5.1, pdal version 2.4.2), I get a
weird behavior where
gdalwarp input.tif output.tif
will change the values in the raster as if it is converting from feet
to meters. My example raster where I see this has georeferencing of
EPSG:3521+6360 and is a 32-bit floating point DEM. My use case would
have more arguments to gdalwarp, but I simplified to the minimum that
showed the problem.
If I change the environment package list for conda to not specify the
pdal version, I'll get pdal version 2.4.3 and gdal version 3.6.2 and
the raster will convert correctly.
I did note that in a setup where it converts the values, I see this
