Why would any of these depend on the preset?
Naming ports seem rather orthogonal to preset plugin state.
In your example, changing a waveform of a synth would first need to save
and restore a preset in order to update a label on the faceplate.
Presets aside, I don't think it's realistic to come up with a schema to
update port labels on a host side UI. Such a concept would need to be
sufficiently flexible, support translations, and retain the layout. Also
for a mixer-strip or gate label, the name should be user-editable
directly in the GUI.
If you need to change the faceplate, custom UIs are likely the best (and
only) way to handle this.
