This seems to be the possibility raised by an article in LifeSite. One of the more amusing quotes is from Cardinal Cormac Murphy-O'Connor, the archbishop of Westminster, who said in an official statement: "The Instruction is not saying that men of homosexual orientation are not welcome in the priesthood." - and adds its own rather dry comment that this is despite the fact that the [ official Vatican] document says exactly the opposite.
What a mixed-up organisation the Church seems to be. I expect that, in practical terms, the new dispensation will quietly be ignored or subverted by a significant part of the Church.
