CF conventions for DAP4?

[Mikejmnez]

I am reading the guide, and Appendix h5.handler section it states:

CF option in this document means to follow CF conventions version 1.7.

CF-1.7 dates back to 2017, and the most recent release is that of CF-1.11. The hyrax guide further states:

For example, since version 1.8, the CF conventions adds the group component into the conventions. But the CF Option for DAP4 and CF Option for DAP2 don’t support the group hierarchy. In the course of time, as funding permits, the HDF5 handler may be updated to support newer components in the CF conventions. Currently the HDF5 handler tries to follow the CF conventions version 1.7 to enable the CF-friendly visualization clients access NASA HDF5 files seamlessly

I know that the DAP4 supports groups by now, and so hyrax supports at least partially CF-1.8. But I am wondering what is the current state of the CF-1.11 that Hyrax/DAP4?
