Hi Steve,
I wouldn't disagree with that argument. If this part of the convention
hasn't found even modest support/adoption in software by now, then it's
probably not going to happen - especially in view of the latest netCDF-4
functionality (although that's not an option for CMIP5, where the
decision was made to go with vanilla netCDF-3 classic, IIRC).
In which case I'd agree that deprecating compression by gathering at the
next version of CF is probably worth consideration.
Cheers,
Phil

Gathering method
Hi Philip,
Compression by Gathering as defined in the CF document is not
widely supported in software. You should anticipate serious
interoperability barriers if you choose to use it. In view of the
option to use "chunked" netCDF4 compression transparently with the
netCDF3 classic API, there's a strong case that the old Compression by
Gathering should be formally deprecated.
