I think they learnt some lessons from hosting the Dodge coin faucet and it will be counter productive for them to open the platform for other Alt coins, because they do not want to create another use case for Alt coins to thrive, when they want people to buy their new token.  

This does not look like a very large operation, with loads of support people that are available 24/7 .... so just imagine if you add 20 extra Alt coins and the support are flooded with additional Alt coin issues.
