Sure but there is no static route required here, or in fact any layer

We'd want it to entirely control if layer 2 pseudowire is, or is not,

What is the MTU on the underlaying paths? Do you have room for using
VXLan over IPv6? Then run BGP + BFD (or even OSPF6) to arrange the
traffic to the vxlan end IPv6 point. (yes, you can do it with IPv4

It's easy if the main problem is a link dropping. It is harder if you
want to have no single point of failure in terms of kit on the way.
My usecase of an above setup was to bridge a layer 2 wifi vlan (and
others) between 2 buildings over a 1 gig ish primary and a 80 meg ish
secondary point to point link. The gig side affected by the occasional
truck in the way. Worked a dream.
Also see https://github.com/FRRouting/frr/issues/3369 - request for
BFD for a static route in FRR. There are links to some other
implementations and usecases.
