Sorry for the late response :)

My conclusion is that we should not change anything about the Scheme
interface, but that with close communication with C port hackers, we can
feel OK about changing the C interface to make it both more simple and
more expressive.  Since libguile is parallel-installable and you have to
select the version of your Guile when you build your project, of course
people will be able to update / upgrade when they choose to.

I put in a lot of effort to the documentation; check it out:
