I am telling you this as someone who had that personal preference for at least 10 years. They are broken and they don't work, the uses cases you use them for can be done better with anything else. I'll go through them for you, keep in mind I am not doing this to challenge you. I am doing this because I have had all exactly the same thoughts as you in the past, and my thoughts all changed when I decided to look at the problem in a different way. In my experience, all that staring at terminals all day messes with one's head, it makes it very hard to see other solutions that could exist outside a very terminal-centric viewpoint.
"I no longer need to alt+tab 7 times to get to the terminal for the monitoring servers, I always know they're on screen 4. need my web browser ? I know it's in screen 2"
Binding an application to a workspace or a key can be done with pretty much any window manager. But you don't want to do that because "screen 4" is abstract and doesn't actually mean anything. You are putting this through an extra level of abstraction for no real reason, it would be better and less confusing just to have some way to identify the correct app.
"Yes you have virtual desktops, but try having 15 open terminals without having them pinned in some form."
This is not actually a good feature of the desktop, this is all a workaround because of the other horribleness of various linux terminal programs that don't offer a good way to distinguish between windows. Also, you can upgrade your GPU you know? It is worth it in general if you want a faster and less laggy display.
"And I cannot emphasize this enough. It's a personal preference."
Respectfully, please stop emphasizing this, it doesn't add anything to the discussion. It is the equivalent of saying "well that's just your opinion". Of course it is our opinions and preferences, but we are here to discuss them. Right?
"if you don't have to tinker in your configuration are you really running linux"
This I think is part of the major problem. The Linux community seems to intentionally gravitate towards things that need more tinkering just for the sake of doing so, and actively resist efforts to reduce the amount of tinkering that needs to happen.
