short answer: yes.

* /etc/sysctl.conf is for users to override decisions distros have made,
  rather than a catalog of those decisions.

* Sometimes we change our mind on those decisions. Flipping a config option
  in the kernel means we push out an update, and forget about it.
  Users /etc/sysctl.conf's contain all kinds of crazyness. ask Davem about
  the stale TCP 'tuning' crap that lingered for years in Fedora users configs
  before anyone noticed.
  (We could update the sysctl.conf at post-install of the kernel package,
   but if you've ever seen a distro kernel packaging schema, you'd understand
   why adding more magic like this isn't desirable)

There's a bunch of patches we carry in Fedora that change defaults because there's
no CONFIG option for them, which I've been meaning to get around to
hacking up into options so we can carry a few less patches.
