It's not kinda RFC (draft), but it's implemented and used in various
other open-source software like FRRouting, Bird, ExaBGP.
It's very handy when dealing with lots of peers.
Exampe between GoBGP and FRRouting:
```
% ./cmd/gobgp/gobgp neighbor 192.168.10.123 | grep -A4 fqdn:
fqdn: advertised and received
Local:
name: donatas-pc, domain:
Remote:
name: exit1-debian-9, domain:
```
```
% vtysh -c 'show bgp neighbors 192.168.10.17 json' | jq .'"192.168.10.17".neighborCapabilities.hostName'
{
"advHostName": "exit1-debian-9",
"advDomainName": "n/a",
"rcvHostName": "donatas-pc",
"rcvDomainName": "n/a"
}
```
