Many publishers don't look a gift horse from voluntary devs in the mouth, if the implementation is acceptable enough.
However, some publishers want to maintain quality standards, especially when they hire freelancers.
Also, plenty of publishers intentionally exclude expansions and/or variants even if the developers are willing to add them.
Anyway, no more thread derailing. This whole 'all losers' stuff has been rejected every time and it will not be changed. Period.
