Ah, as an option, it could work.

How would end users then extract the sources from the DLL? How would
they learn that they even have them in the first place?

Also, people would complain about the increase in size - it's 3.2MB
as a zip file (1,7M as .tar.bz2).

How would that help in not having to distribute the source? Dynamic
linking still requires that the code is available at run-time.
