At least pcap and vde are maintenance issues. They do not even build today.

Off the top of my head, daemon needs fixes to the switch - it has an
O(n) performance hit for n="number of ports" as well as a few other issues.

Tap has a fully functional replacement

Pcap has a fully functional replacement

mcast for 2 instances is functionally equivalent to running l2tp or gre
back-to-back.

IMHO we can start marking some of them as obsolete.
