Thanks.

However, this describes roughly what the code does (which I kinda
understood myself by reading it ;-), but does not explain under what
circumstances would those functions be useful.  By looking at the uses
of split-string-and-unquote, I deduced that the intended use is for
taking apart shell command lines.  If that is not the intent, then
what is it?

The doc strings make very clear that the functions are reversible, but
that in itself does not yet mean they are useful, or for what purpose
exactly.
