Good choice. I was curious so I added it (temporarily) here:

http://us2.metamath.org/ocat/friendship/mmtheorems.html

Who would have known that it depends on Stoic logic? :)

I wrote about something similar that included the /extract functionality 
(but with a much more ambitious goal in mind) in 2014:

set.mm was put on GitHub about 6 months later, addressing some of the 
issues I brought up, and the idea of extract/merge was put on hold. But 
I've always felt /extract could provide insight about a particular theorem, 
and if nothing else would give you an idea of what background you need to 
understand it fully.
