Well, sometimes it *is* new/special in the sense that switch-to-switch
multichassis LAG can be a challenge to implement correctly along with
other features. Stuff like STP, IGMP Snooping & multicast forwarding and
DHCP snooping come to mind.

So even though plenty of kit does it, I believe plenty of kit have its
caveats when using multichassis LAG / LACP.
