Did I really say that?

Adding a WISHBONE interface is a good idea (at least as a configurable
option).  The interface specification is in the Public Domain, which
means that we can use it and still release the F-CPU core under the
terms of the GPL (or any other License).

On the other hand, I want the License to be valid for the whole chip,
up to (and including) the socket it is plugged into.  Users *must*
be able to replace the F-CPU core with a modified version, and that's
impossible if there is any proprietary IP on the chip.

The only solution I can see is a 2-chip approach: make an external
WISHBONE interface and put the proprietary stuff into another chip.
That's no longer an SoC, of course.
