Duopars are awful, unreliable, fragile, quirky, require the unobtanium tabbed washer, display a stunning probability of catastrophic failures, require an unobtanium propriety upper pulley, can’t safely roll backwards, have 2 parallelograms- either one, the other or BOTH can go out of alignment because of the cheap manufacturing, even the titanium looks cheap. And Suntour self destructed trying to chase the Duopar- despite that ANY **** ty cheap, low end Suntour derailleur being better than the Duopar.
Not going to lie, I do see where you're coming from with this. Not necessarily with such vitriol (perhaps I've not worked on enough of them to hate 'em), but when I have, the Duopar has always been a distinct letdown from the hype associated with them.
Full disclosure: I'm biased. Where I live, there's no reason to wrap that much chain. Even a Jubilee is overkill around here

Yes, my Eco gave me headaches. Cheap, stamped steel bends. Proprietary pulleys suck. I had a very esteemed member of the forum "fix" it for me, but I don't trust the derailleur.
My Titane did something goofy- (I think the cage spring slipped off the stop). Based on my experience with the Eco- there's a zillion other derailleurs that are more reliable- and look much better- it just makes sense to replace it.

Might not be your dish of tea, might be quirky and difficult to live with sometimes. But consider these facts, not every C&V bike has Campagnolo type dropouts, some nice bikes have Huret dropouts (not weird on French C&V bikes), those owners can't easily switch to other alternatives.

Now what I'd like is a thicker cassette lockring to close the gap between the smallest cog and the frame, on a rare occasion the chain has come off and jammed in that gap, perfect size for a hard jam, any gap larger or smaller would prevent that. I bought a spacer ring for the back of the cassette but when installing it, noticed that, not only would it reduce thread engagement of the lockring, but more importantly, space the smallest 11 tooth cog off the freehub body splines, enough that I believe it would have been problematic, so I didn't use the spacer ring. A lockring with a thicker end flange, or a smallest cog with same, would do the trick.

The limit screws have springs to keep them in place. If that's not working, try different screws. Then use loctite blue.
If my chain drops from the big rear cog, physics pulls it down to my next smaller cog, not toward the spokes.
For all my rebuilds, the dork disk always goes with the reflectors, steel components, kickstands, and turkey levers: straight in the trash.

Try finding those PBO spokes at your LBS, assuming the wheel isn't trashed entirely due to the great strength of those spokes. I'll use the dork disc. This particular one is pretty inconspicuous.
