I would like to propose moving CNDC to be an "intermediate core" parameter. This proposal is supported by @cabanesc and @coatanoan.
CNDC is by nature an intermediate parameter, being an input to compute salinity. Most floats do not return this parameter; only some floats from the early days of Argo, and some experimental floats, do so. For the floats that do return CNDC, delayed-mode operators need to do a superficial step to fill CNDC_ADJUSTED with adjustments derived from salinity. This is an awkward step, as some salinity adjustments, such as the cell thermal lag correction, should not be applied to CNDC.
In the past, we were not able to designate parameters as "intermediate core". But now we can. Being an intermediate parameter means there is no need to include CNDC_ADJUSTED, CNDC_ADJUSTED_QC and CNDC_ADJUSTED_ERROR in the Argo data files.

update the file format checker to manage CNDC as intermediate core parameter. No more adjustment on CNDC parameter : CNDC_ADJUSTED, CNDC_ADJUSTED_ERROR (CNDC_*) should not be reported in Argo NetCDF files.
update the DACs decoders to remove CNDC_* from real-time adjusted files
Should we (?) update the delayed mode data processing chains to remove CNDC_* from delayed mode files
