What is the benefit? /var/run is well known and established; what is
the reason to move it in another place?

They are not really abstract sockets anymore, are not they? (Not
really related, but just wanted to confirm)

Please, no. When it runs, /var/run should be equivalent of /run (or
whatever). If it is not - distribution has reasons to not do it; not
everyone can switch to tmpfs overnight. Leave it at /var/run as to not
break existing setups. It will work for both cases.
