Thanks for looking into it.

I sympathize, and I agree that is difficult to fathom.
Can't help with the understanding, however.

Dunno.  But just because the code can be difficult to follow
is not a reason to assume that it does unnecessary things, in
general.  The widget code that I've been able to follow does
DTRT, generally (AFAICT).

I doubt that anyone left understands the widget code well.
Maybe you can find Per Abrahamsen and get him to take a look?
The URLs for him listed here are dead, but maybe looking here
would be a start: https://www.emacswiki.org/emacs/PerAbrahamsen.
