[netcdfgroup] Quantize Support in netCDF-Fortran: Only Bit Groom possible?

netCDF List,

I am looking to extend the model I work on, GEOS, to support using the new 
quantize options in netCDF. My question is: am I right in my reading of 
netCDF-Fortran that only Bit Groom is supported?

I can see in netCDF-C that there seem to be three variants:


  *   Bit Groom
  *   Granular Bit Round
  *   Bit Round

(see https://github.com/Unidata/netcdf-c/blob/main/docs/quantize.md)

but in the netCDF-Fortran docs I only see it mention Bit Groom and my reading 
of the include files seem to back that up.

So I was wondering: Is there a fundamental Fortran reason for not supporting 
the other two variants? Or perhaps, is it that, of the three variants, Bit 
Groom is by far the one people should use, so that's what was exposed by the 
Fortran interface?

Thanks,
Matt
