Hmm, since when this limit exists? Looks like it was introduced after 2.4.20-28.9 (RHL9 kernel) One of my newer public servers (running upper shown kernel version) have already 23 IPv6 addresses: # ip addr show dev eth0|grep 2001 |wc -l 23 Mostly used for one IPv6 address per "on-IPv6-no-longer-virtual-IP-less" Apache2 webserver. So I have the same opinion like Pekka, 16 would be a little bit to view, 64 would be a good default value for the limit.
