Why not?  Most debuggers will always be out of tree for political
reasons, and because of that the normal "every hook must 
have an in tree user" rule cannot be strictly applied to them.

It's also not reasonable to ask these people to always 
carry big patchkits around - after all they just want
to debug core kernel code, and it is very ugly to apply
a big patchkit just for that.

So as long as the hooks for external modular debuggers 
are reasonable and _GPL I think they should be merged.
