More than easy, it should be obvious.
Obvious doesn't mean easy, it just means what you have to do to get it
right is clearly in front of you. When you give people the freedom of
an "archive command", you also take away any guidance more restricting
options give. I think the point here is that a default would guide
people in how to make this work reliably, without having to rediscover
it every time. A good, *obvious* (not easy) default. Even "cp blah to
NFS mount" is obvious, while not easy (setting up an NFS through
firewalls is never easy).
So, having archive utilities in place of cp would ease the burden of
administration, because it'd be based on collective knowledge. Some
"pg_cp" (or more likely "pg_archive_wal") could check there's enough
space, and whatever else collective knowledge decided is necessary.
