I think what most people, including tiling people, would actually want without realising it is Divvy (macOS)/gTile (gnome)/PowerToys (Windows).

A regular floating window manager but you can move any floating window into a tiled window based on a grid of potential locations.

It's hard to explain in words but look any of them up and it's the best no-compromise solution for everyone.
