Matthew Schmitz:

If the church really does believe that homosexual acts are always and everywhere wrong, it should begin to live what it teaches. This would most likely mean enforcing the 2005 decree and removing clergy members caught in unchastity. If the church does not believe what it says — and there are now many reasons to think that it does not — it should officially reverse its teaching and apologize for centuries of pointless cruelty. 

This is exactly right. Refusing to change its teaching but also refusing to uphold it is the worst of all worlds, theologically, morally, and practically.
