They do actually.
The four pair version of 100Mbps Ethernet fell by the wayside back when
Fast
Ethernet
products were first shipping. 100 base TX as in use today uses only two
pairs:
pins 1,2 (orange pair in 568B)
and 3,6 (blue pair in 568B)
I have used line doublers on fast ethernet, and also (with a custom
cable)
to feed ISDN and Ethernet down the same CAT-5 cable
