Do the Rogue Pits of cemeteries still exist?

In the not-so-good old days, there used to be an annexe to the Christian cemetery, called Rogue Pit in some places, where members who had commited suicide or had lived sinful public life would be burried. These days, such annexe is hard to come by. I wish to know whether the Catholic Church has officially stopped segregating a part of the cemetery to be used as Rogue Pit, or has the practice tapered off without invervention of of the Church authorities .
