I mean that the code that would have been in the dll and loaded into
Wine should be in the debugger instead. So for instance, instead of
having a magic key (or X message) to switch tracing on, you'd have a
debugger command 'set tracing on' that would poke into the Wine
address space to do it. Since you can read/write memory, call
functions (I think it's broken now but should be easy to fix),
etc. from the debugger you can do everything from here and avoid the
need to have any debugging code running inside the Wine process.

Yes, exactly.

It would certainly be possible to load dlls inside the debugger itself
to extend it; though maybe simply loading a batch file containing
debugger commands may allow to do a lot of things already without
requiring compiling new code.
