You may have missed the 'ping' to the list just this morning about a patch to
add a new Header keyword (that was originally submitted in March 2008). And you
also may not recall that there were a couple of keywords added initially outside
of CVS that relied on custom clients for a time (the *BSD people in particular,
see below).

The keyword system was rewritten some time ago in the hope that we could come up
with a way to provide server-specific keywords (e.g. the *BSD people want to
recreate their CVS hack to only expand their own keywords on stuff imported from
the other streams). If we could come up with a server-distributed configuration
file, custom keywords would be (at this point) relatively trivial to add without
having to distribute custom clients.

Not so. Some/many people are limited (by corporate policy) to only installing
packages from a single source (think RedHat Enterprise Server), so there is
frequently a significant gap between a new core release and distro releases.
RHEL4 is still technically stuck on Subversion 1.1.4 and RHEL5 is still shipping
1.4.2 (even the just released 5.2). You have to go with a third party repo like
Dag's RPMForge repo.

Properties have definitely not been given the care and feeding that some people
would prefer. I suspect this may be due to the feeling on the part of some
people (me included) that keywords can quickly lead to "action at a distance
magic" that is extremely hard to deal with (think the $Log$ keyword in CVS for
