That's quite fortunate/fortuiutous and makes for a nifty shortcut that works so well. Is this common for all terminals, eg does gnome-terminal have a --class that would let it slot in to this .desktop setup?
Tbh the Mac version looks a bit too involved and hinges on or works around specific behaviors, I'm not sure I'd want to go that far as it then ventures into the territory of 'maintenance'.
I use X window classes to differentiate between all of my Firefox instances. No idea if Wayland even supports the idea of window classes (so that I can raise the instance I need with a single hotkey), but if not that’s yet another blocker for me.
https://github.com/fmoralesc/neovim-gnome-terminal-wrapper also exists if you want to go that route. I tried it for a little while and it worked pretty well, but it's not particularly easy to re-use for other applications.
The mac version is a bit of a pain to set up the first time, but it's pretty straightforward after that!
