That would be great.

The nearest we have is swank-backend.lisp. That is a clean and
documented specification of all non-standard functionality that we
need from the backends. This interface is not generalized beyond our
own immediate needs though so one wouldn't adopt it as-is.

In swank-acl.lisp you can see that ACL's debugging API supports our
needs fairly directly.

I think the SLIME<->SWANK interface has been changing incompatibly
much more than the SWANK<->SBCL interface in our history so far.
