Lots of LIR don't practice this, they kind-of encourage NATing by giving
their users a few public IP and when the user ask for more, they attach a
fee to it. A typical ISP gives max of a /28 for free and everything beyond
attracts an extra fee. You can imagine a typical institution with over
40,000 users assigned a /28 for use.

You made a valid point, an scenario is having a /16 advertised and using 1
for NATing and say another 4 as DSNAT to internal server running private
IP. This has become normal practice that is almost turning to a culture.

+1 and good for you by doing that. Just to ask, do you in anyway check to
confirm if your customers are indeed utilizing the requested block?

You can say that again, it may shock you to know that the provide is a
major ISP in the continent!
