Thanks Quentin,

As of about five minutes ago I've solved this with a bash script called by
networkd-dispatcher that adds and removes the routes associated with a given
next-hop.

Getting it to behave safely was a bit of work but it does the job I need it to
do and it's more than fast enough.

I would _far_ rather FRR had proper object tracking capability like mainstream
appliance routers do so it could all be captured in the config file, but this
works.
