Tmux prevents vendor lock-in but on Terminal level. It's so established and standard that everyone knows they need to support it, which is great. I don't need my terminal do display pictures, render video or whatever crazy features they come up with next, I want a solid base with the essentials.

The rest the Operating system applications can probably do better anyway. VLC, MPV, Apple Preview IrfanView etc.

That's why I love Alacritty, no fuss, no overcomplication. The basics, fast and stable.
