We do have them.
Most popular DEs already support tiling with extensions (Gnome and KDE).
KDE actually added native support, although pretty limited so far.
IMO the tiling support in KDE and with gnome extensions does not look great. It cannot replace someones workflow that has been on a true tiling window manager. It is a benefit to those that have been using floating window managers for their whole life but I cannot now go back to them. Cosmic is the first desktop environment that looks like it has true tiling support (that can rival a tiling window manger) and not just drag a window to a side/area of the screen. Though I have yet to really try it out.
This. It’s not well-advertised in KDE – I accidentally discovered it through a key combo – but it was good enough (i.e., Win 11-level) in KDE 5 to make the switch painless on desktop. Where both have issues is apps insisting there are arbitrary dimensional minimums for functionality and refusing to adhere to positioning. This is most egregious in messaging programs.
On KDE you can try out Polonium, which integrates with the native tiling support and makes it awesome!
I’m currently using KZones, actually, it’s not automatic, but it works pretty great.

This looks quite nice as well
If you’re still on X11. Krohnkite didn’t support Wayland all that well last time I checked.
