FWIW to upcast the cube's new coordinate to a DimCoord (such that when saving NetCDF the dimension name comes from the coord's var_name) one would need to do:

import iris.coords

tbd = cube.coord('tbd')
tbd_dims = cube.coord_dims(tbd)

# Create a new coordinate which is a DimCoord.
dim_tbd = iris.coords.DimCoord.from_coord(tbd)

# Remove the AuxCoord and add the DimCoord.
cube.remove_coord(tbd)
cube.add_dim_coord(dim_tbd, tbd_dims)

I like finding answers to questions that I wrote many years ago. That still work today! 🎉

Just wish I'd implemented multiple coordinate sorting, not just one...

I guess it would work just as well to split the cube into single length items on the dimension to sort then to merge them together again...
