Hot take alert:
This is a stupid opinion.
First, the article reads like an AI wrote it, but assuming that's not true, the Linux space absolutely does NOT need more tiling window managers.
Quite frankly, I'm amazed there are still as many actively developed ones as there are.
The VAST majority of Linux users have little to no interest in a tiling WMs, and the basic tiling features of Plasma, Gnome, and soon Cosmic are fine for most of the users that want to try it out. The few that really want hardcore full tiling are almost always already very experienced power users who know what they want and how to get it. They aren't going to be put off by their favorite distro not having built in support for tiling WMs.
In fact, most of them are already using distros that are able to be heavily customized to their liking, like Arch, NixOS, and Gentoo.
How many users do you think want to run Linux Mint or PopOS but with some hardcore tiling WM?
Linux has a massive amount of variety in all areas, it's already hellish for new users to pick a distro from the forest of suggestions, do we really need even more tiling WMs on tip of the dozen+ ones that already exist and serve a tiny percentage of Linux users?
