But that happens for every service adding new config really. The pain
for a total rework for Horizon's config layer would be felt by everyone,
and not everyone would want it.

I like the ability to make it custom! But then again I'm used to Django
What really bugs me with Horizon is the enabled files for managing
panels/plugins etc. That's a nightmare to deal with depending on where
you deploy it and what panels you want. These days we build one big
Horizon container (all panels, all themes), and then on start up it
reads our custom config and copies/deletes the enabled files you want:
We used to control plugins at build time, but that was worse. Not being
able to change which plugins were enabled when starting/restarting the
service was painful. With this, we can stop the container, update the
config, and on the next start it will setup the panels/plugins we want.
This used to be a NIGHTMARE with puppet.
Better config in general is definitely something to think about if a New
Horizon ever happens, although non '.ini', because that's too limited a
