There were at least 2 good reasons for that :
There had to be an easy way to disconnect your wiring from the network so that BT could tell if the fault was in their stuff or yours.
The ringing voltage (and possibly the DC 'battery' line voltage) was high enough to be classed as hazardous. So connecting to something connected to the phone line was not something for J-random-public to do.
Connecting to a plug (either a normal BT plug to go into the original master socket, or the NTE5 faceplate) which was plugged into the line at the end of the job solved both of those issues.
