We have not yet begun to implement support for ragged arrays.  The
concept (and a possible implementation) was developed by Harvey Davies
in consultation with us.  Harvey is coming here about a week for,
I believe, five months, to work on ragged array support and other
netCDF-related things.

I'm afraid that's as time-specific as I can be.

If you have further questions, please feel free to contact us.
