Just use Rectangle app https://rectangleapp.com/
It integrates in the way I would expect the native feature to work: hover the green button for a snapping palette.
I'm not saying moom doesn't have those, I just haven't used it and Rectangle serves my purposes perfectly well.
To each their own, of course. Just trading anectodes. :)
The best possible outcome is you get an ex-Apple engineer who may have some background as to the thought process.
