The primary reason that pops to mind is backwards compatibility...
Ubiquitous availablity of the
parts for RJ45 connectors (end connectors, wall plates, panels, etc.)
also means that it is more
economical to continue using the well established connector. A new
connector would
drive up costs initially, whereas continuing to use RJ45 is cheap and
already works.
