We'd love to have such an extension included directly in jackrabbit-webapp, so it would be
great if you were interested in contributing one!

My typical recommendation is to do such administration-level tasks (node type registration,
workspace creation, etc.) using a local repository instance, which both of your suggestions
implement. See also https://issues.apache.org/jira/browse/JCR-836 for a related feature idea.

Correct, here's the relevant backwards compatibility note from Jackrabbit 2.0:

  * The JCR-RMI layer no longer implements the Jackrabbit API extensions.
    Code that uses JCR-RMI with distributed transactions or for administration
    operations like creating workspaces or registering node types needs to
    be updated accordingly.

> Is there a particular reason they are not supported?

There were some complications in having JCR-RMI support the Jackrabbit API extensions while
still keeping it usable for non-Jackrabbit repositories, so the support for those extensions
was dropped. The plan is to re-implement the same features using the now standard JCR 2.0
APIs, but so far nobody has had time to do that. Contributions in this area would be very
much welcome.
