Yes, adding a "<when else>" option would be nice. However, what I really would like to have is a way to tell in one select box which other select box(es) should be refreshed when its value is changed by the user. For example:
<param
name="cmb_col_type"
type="select"
label="Select column type"
param_to_refresh_on_change="cmb_polarity"
display="radio"
dynamic_options='get_column_type(library_file)'
help=""
/>
<param
name="cmb_polarity"
type="select"
label="Select polarity"
display="radio"
dynamic_options='filter_column(library_file,cmb_col_type)'
help=""
/>
So when cmb_col_type is changed, the dynamic_options of cmb_polarity are generated again by a new call to the function configured. I can create a Trello card, but I’m just wondering whether this is not already being planned by the team,
especially with the Javascript/AJAX rework that is now planned/going on(?) for some time on the user interface?
Regards,
Pieter.

This is deliberate, although there has been talk of updating the conditional code to do the dependent parameters dynamically rather than server-side with a page refresh.
From your outline description, I think you should be using the Galaxy <conditional> tag.

I think you are right - I've asked in the past about this, e.g.
this discussion which appears not to have been fully on the mailing list though:
This probably deserves to be tracked with a Trello Card...
