Is it worth fitting a new water pump while having the cambelt changed?

I have a DS3 1.2 PureTech 110. It's a 2016 and has done 52000 miles so I am booking it in for cambelt change. Should I have water pump changed as well?
Changing the water pump is not necessary but some garages recommend it because the work involved in changing the belt gives them easy access to the water pump. Therefore changing the water pump should cost no extra labour ( just the cost of the pump) and is really a belt and braces approach. Water pumps rarely fail but for the little extra cost, it's worth doing if you intend to keep the car for several years more.
