I couldn't find these patches in my inbox but my concern would
be that at some point panel-simple will turn from simple into
panel-rube-goldberg-machine.

Given that the talk with the manufacturer may result
in even more quirks... maybe this should just be a separate
panel driver?

(I expect pushback because I see how handy it is, but
I am the guy writing new panel drivers all the time rather than
using simple.)
