Yeah, at the end of the day something needs to mediate between services
that need to update your DNS information.  If you're using
NetworkManager, then NM does this mediation for you for things like PPP,
PPtP, DHCP, openvpn, and vpnc.

But if you're not using NM, each service (vpnc, dhcp, openvpn, pptp,
ppp, whatever) has to have it's own logic to backup and restore
resolv.conf.  And that just sucks.  Some distros have resolvconf to help
with this, which does the same sort of thing as NM and "stacks" DNS
configs.  Most of these hacks are standard *NIX: everything has it's own
system and nothing works very well.
