I was referring to this:

Search for "a separate binary ... oh come on"

 From the very beginning I knew such changes would never be 
upstreamable, that's why I thought creating a separate binary was the 
cleanest solution.

Regarding implementing it as a separate applet: I don't think it would 
have been a good idea because you would have to either add a dumb icon 
to your panel so that you could run this system, or add an invisible 
applet (not handy for the user to manipulate). Keep in mind that the 
binary is started on demand, so it does not take any memory if you are 
not using it (assuming it would automatically stop itself after a while).

The alternative of using a kded module could have been a good idea, but 
it would have required the creation of a kcm to configure the system. 
Such kcm would have had to tweak Plasma system tray settings behind its 
back, which could have been a problem to get on the fly changes. It 
would have at least needed to patch the applet to tell it to stop 
listening on dbus.

(admittedly, a separate binary would have required a kcm as well)
