In other words, once a font has been loaded, those parameters are only informative, and changing them is useless.
This _is_ while loading/creating the font. I am using a setup similar to
without going through the callback but directly defining the font:
num = font.define(f)
\name this is in the font f
So how to create the ghost fonts here?
