Well, really, it's more of a "non-note" on celibacy for incoming Anglican ministers
Because the note portends no change in the law of celibacy and no change in the process by which married candidates from Protestant denominations can petition for and, if selected for orders, be exempted from the law of celibacy, what the Vatican Information Service calls a "note" seems more of a "non-note".
Resources: Good information on the "Pastoral Provision" under which (primarily) Anglican married ministers have received Catholic orders; a Wiki overview of the Pastoral Provision with texts and links to important documents such as Sacerdotalis coelibatus and "In June".
