It is possible that my concern was misplaced. My thinking was that if the 
two bindings were logically separate projects, rather than being 
variations on the same code, we should keep them logically separate in 
Guix even if they are superficially similar. However, it might not be a 
logically separate project, and that might not be the right way to think 
about it anyway.

I don't have an objection to the version using inheritance. I am still 
curious in learning about the differences between the two packages if only 
for my own edification.

Hopefully that clarifies, and sorry for adding noise to this review.

Best,
Jack
