We use this on some graphical Debian servers at work. I hate it. The servers are beefy and the displays have high resolitions. There is no technical reason for having to use IceWM. Our 63-year-old veteran colleague simply likes it and blocks suggestions to move to a modern minimal WM. There are better options in big 2026. I cannot wait until he retires, so that we can retire IceWM.
What are the better options? I've been out of the game for a while and just been using Gnome.
There are about 300 people working daily on these servers. I'm team "enlightenment" and got about 50 people supporting me. There is the i3/sway camp (30ish people), there is the dwm camp (10-15 people), and there is the "please anything with modern UX at all" (estimate: 200 people).
I remember at university, we'd all log into our remote X sessions at the start of a lesson. I used blackbox back then which zipped along quite happily, but 30 people all trying to boot up KDE 3 at once rarely went well. I'd say careful what you wish for, but I assume modern servers can handle this better.
dwm may be worth a look: https://dwm.suckless.org/
