Multihop BFD support on OpenBSD

Hello OpenBSD Team,
I'm Sudarshan, a software developer at NetApp. cc'd are my colleagues at NetApp.
I have been going through OpenBSD's BFD implementation<https://github.com/openbsd/src/blob/7853af7355314b198e29153656858f98a017f6c9/sys/net/bfd.c> with an intention of using
it for one of our use cases. While doing so, I realized that OpenBSD currently doesn't
support multi-hop BFD(RFC 5883).
https://github.com/openbsd/src/blob/7853af7355314b198e29153656858f98a017f6c9/sys/net/bfd.c#L797-L798


1. Is there a plan to add BFD multihop support to OpenBSD in near future?
2. Also, is there a plan to add a portable version of BFD to other platforms like FreeBSD and linux
similar to OpenBGPD?

Thanks,
Sudarshan
