the latest 4.0 library supports writing netcdf-3 large files, but
not netcdf-4.
i doubt performance is a good enough reason to do all that work, but
it would be interesting to see some timings.

only to support netcdf-4 writing, and its still a maybe.
the issue from my POV is what API do you implement? we will
implement the Java-Netcdf IOSP interface. We are experimenting with
JNA, which uses reflection to make the programming easier, at the
cost of some efficiency.
