For your more typical router-to-router links, then by all means, use a /64, /127 or anything else you feel like. SR OS supports this too.

Not sure if this is still valid, but I had issues using /127's on ethernet links a couple of years ago.

My end (RouterOS) assumed the first available address to be the��Subnet-Router anycast address, and listened on both addresses.

Had to negotiate swapping the addresses with the other end to make it work.
