Consider this: The static init cib is stored, the user starts the
cluster and waits anxiously for the configuration to load, it's
loaded yeah!, but there's a problem with resource x, let's see
where's the issue, reading a few thousand lines of log, aha!,
there it is, fixed, works!, great, everybody happy, everybody
forgets about the static init cib; then next month there's a new
release, put resource in not managed mode, stop cluster, upgrade,
start cluster, load static init cib. That is bound to happen.
What's wrong with cibadmin -C? Or crm configure load replace? One
can even load from an url.

Thanks,

Dejan
