I tried a handful of terminal in Linux and it appears that while the 
majority support OSC 52, a significant amount of them don't. The biggest 
gap is all the vte based ones like Gnome Terminal or XFCE Terminal. 
These are their windowing system's default terminals, so there's likely 
a lot of usage here.

If we want to ensure mouse drag to highlight, copy within the terminal 
Emacs, followed by a paste outside of the terminal still work we would 
need to bring xclip into core. I think this would be generally good to 
do anyways. I didn't know about the xclip package and it would have 
significantly improved my workflows with xterm-mouse-mode. I suspect 
many other users of xterm-mouse-mode are in the same boat.
