While T-vector cloning is commonly used for PCR-amplified inserts, restriction enzymes still have their uses. For example, you can ensure directional cloning if you digest a vector with the same two enzymes like BamHI and EcoRI that are used to digest your insert. This way, the insert can only be cloned in one direction. However, there are other cloning techniques that can be used to modify the end of vectors and inserts after restriction enzyme digestion and prior to ligation.
