To make my patches less 'invasive', I'm contemplating to move them to a separate gdb target, e.g. 'target sis'. Then I will not interfere with gdb's internal simulator and I can add things like hardware watchpoints which is not on the interface to gdb's internal sims. I will see how realistic this is ...

Would adding a remote server be something you would consider? This means you can
be separate from GDB.
