Emergency Escape and EXWM

[port19]

Hi all,

while reading the emacs manual I stumbled across a little inaccuracy in
(info "(emacs) Emergency Escape")

> Emergency escape is active only for text terminals.  On graphical
> displays, you can use the mouse to kill Emacs or switch to another
> program.

While this is true for the vast majority of graphical sessions, one major 
exception exists.
On EXWM, not least due to the single threaded nature of emacs, the graphical 
session can indeed hang because of emacs.
In this case it's not possible to kill emacs with a mouse or switch to another 
program.

This has only affected me a few times in the 10 months I'm using that window 
manager.
For me, not having emergency escape is acceptable, as I know to switch ttys via 
e.g. C-M-F2.

Should this be documented? 
Should emergency escape be available via a customization option to graphical 
sessions?
Or is this minor enough to ignore?

Your call.

Best,
