Uhmmm... you never know!  ;-)   ;-)

Yes -- and it very likely would mean that a lot *more*
computers without the nomachine-key running (and even 
without NX running) are also compromised by the same

You force each NX server admin to create their uniq key
(and maybe apply one common key to each of the NX servers 
under their command) and force each user to install a key
(possibly for each NX server they want (or are forced) to
connect to, and you create an administrative overhead (and
troubleshooting) for this. You are trading a bit more 
security for a bit more work and worse usability...

That's fine (don't misunderstand me here, please) -- it
is *your* choice to do so. But please don't remove the 
options from others to choose differently (after they
have been made aware of the implications). Don't force
your personal choice (how you weigh security against
comfort and usability) onto the general public of current
NX users.

Regarding your other suggestion about improving the !M
NX and the kNX Client GUIs so that they make handling
of different key pairs easy to users: I believe this is
a very good idea -- and, in fact, this has already been 
discussed for the kNX client (no code yet). Also, if I 
am not mistaken, similar plans do also exist on the !M 
side of this project. So it might not be even very long 
before we see it materialize....
