There are still applications that break with subnet smaller than /64, so all

Wouldn't that argue for /64s?
/64 netmask, but not /64 for a customer. There are application which
break if provided with /80 or /120, but I am not aware of an application
requesting /64 for itself.
/64 for one customer seems to be too much,
In what way? What are you trying to protect against? It can't be address
exhaustion (there are 2,305,843,009,213,693,952 possible /64s in the currently
used format specifier. If there are 1,000,000,000 customer assignments every
day of the year, the current format specifier will last over 6 million years).
Too much hassle, like too big config of your router. If you have 1000
customers in a subnet, you would have to have 1000 separate gateway IP's
on your router interface plus 1000 local /64 routes.
