Writing cell array of strings to hdf5 using h5write

The hdf5write function lets you to easily write a cell array of strings to an output HDF5 file. However, the documentation states that hdf5write will be removed in the future, and to use h5write instead.

But h5write only supports numerical types, and the documentation states that you need to use the low-level H5D functions in order to write strings.

When will h5write be upgraded to support string writing?
