This is intentional because $ifconfig_IF_ipv6 is designed as
per-interface version of the old $ipv6_enable. I added an explicit
description about this to rc.conf(5).

$ipv6_prefix_IF is the counterpart of $ipv4_addrs_IF. It is limited
to /64 prefixes, though.
I didn't notice it said ifconfig_IF_aliasN was deprecated. Although
the man page explains the depreciation is due to a difficult behavior
of _aliasN, if it is the reason, it is easy to support multiple lines
in the variable like this:
ifconfig_em0_aliases="
inet 192.168.0.1/32
inet 192.168.0.2/32
inet 192.168.0.3/32
"

Moved it to just after a normal GUA configuration example in rc.conf(5).
