ERA5 netcdf encoding since the new CDSAPI release

Hi,
I noticed that the result of requests in netCDF format for ERA5 product (reanalysis-era5-single-levels) are now declared in double precision. Before, the results were in short, with add_offset and scale_factor to convert values (done smoothy by a lot of softs, ferret ncview, xarray etc)
In my mind, that change have 2 inconvenients :

  • increasing the downloading time,
  • increasing disk usage on both side, ECMWF, and on my side
    I understand that the new cdsapi extract data from a pool in grib format. But why to drop out the previous encoding in netCDF format ?
    Thank you
