I probably should have tried this sooner, but yep, the PostUp works by 
stealing what wg-quick is doing with resolvconf, and if you also also 
set DNS nameservers in the same statement:

PostUp = echo -e "nameserver fd00::1\nsearch lan.example.com 
lan.ipv4.example.com lan.ipv6.example.com" | resolvconf -a tun.%i -m 0 -x
