Re: Do you use or see FQDN capability?

I'm guessing this capability will just sort of live on forever, rarely
used until, if ever, those software implementations decide they want to
remove it.

Considering that router IDs may be arbitrary numbers, I expect more
hostnames to be seen on the BGP sessions. In a network where the BGP
links establish more or less automagically over link-local addresses,
all the legacy stuff uses RFC 8950 and router ids are more or less
random, hostname is the only reasonable thing to set to identify a host
well.

Also there are still 15+yo implementations out there in the wilderness,
you can't expect people to eagerly update everything just to use the
hostname capability. Its use will simply gradually increase as new
deployments roll out.

Last but not least, it doesn't help at all that this is a long expired
draft, and it deserves to become an RFC.
