If you pulled these module(s) you want to take code from out into a separate
library, published it on github and sent a request to the original author(s)
to adopt this as a separate dependency, there would be a bit more granular
reuse going on. Naturally the original authors might reject your dependency
for their code, but with the right metadata available in your new library,
others would be able to discover and potentially also use it.

But they ought to learn about them. Making releases and
libraries/applications the standard unit of distribution and dependency
use/reuse (as rebar, agner and other tools do) should reinforce this and
encourage people to learn.
