For gdalwarp (GDAL 2.3.1), using -dstalpha (hoping to get transparent pixels outside the original image area) ala
gdalwarp -dstalpha -srcnodata 0 -t_srs EPSG:4326 in.tif out.tif for an input geotiff RGB image (created by gdal_translate) I get an RGB output image, not an RGBA as I expected. From googling, it appears -dstalpha works for others. This seems so simple, cannot understand what could be going wrong.
