Well, I certainly agree that it is nice to have such a feature. My Problem
is, that the 3.5 mm connectors tend to wear out quiet fast so I'd like to
not pull them in and out multiple times a day...
A bad contact gets very annoying and is not good for amp or headphones
either I think (you know, the loud crack when you put in the plugs while the
amp is running)

A crude/basic workaround would be to use something like this command:
$ amixer -q set Headphone toggle && amixer -q set Front toggle
This assumes you have one of them muted and the other unmuted and
it'll simply toggle their states.
You can assign this command to a _custom_ shortcut in the
gnome-control-center -> Keyboard and assign some hotkey or key combo
to invoke it.
