Somebody's Knockin' At Your Door
It seems to me in this case we have an example of a custom that, while no longer mandated, is certainly not expressly forbidden, and thus is a part of the liturgical patrimony that we can (and do, in many cases) retain right now. After all, it would be a kind of rubricism to presume that just because the liturgy does not prescribe something like this, that it therefore proscribes it. It would be good, then, to seek to implement this custom in the future, since, as the Pope points out, it clearly symbolizes for us Christ opening the doors of the world and of our hearts. For those prevented by doing this from exigencies such as glass doors, I would recommend using a liturgical clapper to simulate the effect without potential damage.
Here's hoping the Pope's reference incites some discussion of this practice and, more importantly, its wider use.
