Option to deal with pixels at nodata as if they were valid in `gdal raster proximity`

[VaasuDevanS]

Feature description

gdal raster proximity takes nodata from the input raster into account and is not calculating and assigning distance values. -use_input_nodata option in the old api solved this issue.

Reference: https://gdal.org/en/stable/programs/gdal_proximity.html#cmdoption-gdal_proximity-use_input_nodata

As a workaround, I am setting the nodata to none using gdal raster edit, calculating the distances and then setting it back to the original nodata value.

Actually, no. gdal raster proximity does enforce USE_INPUT_NODATA=YES . So what you would want would be a --ignore-nodata flag. I'm not totally sure how common that need is to justify adding this flag.
