In general, yes, our policy is to unbundle things when practical.

But there are some commonly used software implementations of basic
functions (like base64, sha1 (most hash functions actually), et cetera)
that are specifically designed to be copied and pasted into the
application that will be using them.

You can usually tell this is the case because the thing will not have
any build system at all, like you suggest. Also because you find the
same copy-pasted code in almost every program you look at, like with
base64 and the hash functions.

Well, at a certain point it becomes a matter of taste, and the choice
should be made by the person doing the work — you! Either way is fine
for Guix :) The important thing is to get this Teeworlds fix pushed
without too much delay.
