As Deezee has said, its not life changing
but it does make it easier to install / and or for future maintenance & also makes it easier when feeding the inner cable thru as you won,t need to remove the inner cable from the sheath IF you are intending to shorten the cable at the nipple end .
I found that shortening the cable at the nipple end meant that there,s no need to join 2 halves of cable under the handbrake lever ( not alot of space there ) & I suppose being honest looks a neater installation,
I used a 1mm cutting disc in a grinder to slit the bracket, just wide enough to wiggle the inner cable thru the slit.
