[OpenWrt-Devel] firewall instead of routing rules to keep ULAs from escaping

I wonder why in https://dev.openwrt.org/changeset/35012 the choice was
made to use the firewall to prevent ULA destination addresses from
trying to be reached on the WAN vs. using routing rules and
"unreachable" routes.  Something like:

unreachable fc00::/7 dev lo  metric 1024  error -128

in the routing table for example.
