Interesting topic, this was also relevant to me some years ago when I started dabbling in twm, esp. i3wm in that time. To this day I am using i3 because its “easy” to set up for me and I started using a repository on codeberg.org for version control of my dotfiles (www.chezmoi.io).
I am also torn on the subject of using twm nowadays, at work I am using i3, but at home I am still in the woes of a fully fledged KDE. I love to work on the terminal and prefer most applications to be cli based instead of having a full gui. But recently I finally took the plunge on trying a multiplexer (zellij.dev) which actually makes me think, twm are not really that necessary once you start using a terminal multiplexer.
**Because what you will notice is that it doesn’t make a lot of sense to tile ALL of your windows all the time, mostly its for cli applications, which is handled by the multiplexer in a perfectly fine way.**Also when it comes to eye candy…with twm you will mostly never see your wallpaper, apart from some artificially created layouts which you can post on various *unixporn sites.
While you want a lot of windows as fullscreen, depending on your screen size. (most videos, browser etc.) So maybe you don’t really need a twm and can instead work with any lightweight window manager, the beauty of going non-fully-DE is that you can mix and match all your favorite programs however you like! Take a look at and check out some of those git pages maybe you find something which suits more to your needs: wiki.archlinux.org/title/Wayland#Tiling
