Having the source code would probably be good for things like Project Carrot though.
Plus it might include the JCS source code, so a JCS+ might be possible. :P
(Yes, I'm aware of MLLE and WebJCS. Both of those are in beta. Adding a couple of small things to JCS like upside-down tiles would make such features infinitely easier to access)
Also, there'd probably be some commented out code and such from unfinished things that are completely unrepresented in the compiled files.
Not saying it's any more likely it'd happen(Although if Epic ever re-release it on GoG or whatever, I think it'd be worth them considering doing so), but having the source code wouldn't be totally useless.
