Yeah, that sounds odd to me too. If we allow symbolic values in a 
defcustom, somewhere in the same package there has to be a mapping 
between the symbols and the functions corresponding to them. Which would 
have to refer to a function from project.el in this case.

Of course, we could alternatively have some sort of registry for 
third-party code to jack into upon loading or etc, but that sounds like 
a massive overkill for this case.
