Can be done.

This practically will totally limit any contributions as not every
Hatari user has TT and Falcon and clones in their focus.

I strongly object. This should be done by someone who knows these
special cases and can decided what is correct and what not and then
improve on user contributed patches.

I cannot in this case.

But I will gladly take a decent GUI that incorporates all convenience
features derived from the crude CLI debugger features present so
eliminating the need to add new CLI features.
