As someone who uses Linux on all my personal machines but has usually had to use a MacBook for work, tmux is also pretty useful as a platform- independent tool for me to reuse the same workflow without needing to worry about differences between the two. I use Alacritty on Linux, but when I've tried using it on MacOS, there have things that don't seem to work for me out of the box the same way they do in Linux (which I'm struggling to remember exactly at the moment, but I think one of them might have been the setting to have the window maximized on startup). Rather than spend time trying to tinker around on an operating system that I don't have any particular desire to use outside of just getting my work done, it's pretty nice to be able to use tmux on iTerm to get basically the same experience I do on Linux. From that perspective, having something like an entirely independent way of scrolling back in a session is a feature to me, not an annoyance.

A lot of these arguments against tmux seem like they're more relevant to someone developing a terminal rather than using it. It's fine for people working on their own terminals to decide they don't care to support it, but I don't really find the arguments convincing as something I should care about, and I'd personally just switch to another terminal with better support for it rather than stop using it.
