But even better if you turned guestfs_feature_available into a
non_daemon_function, added a new guestfs_internal_feature_available
daemon_function, and then cached the results on the library side.
They can never change for the duration of a libguestfs library load,
as far as I know.

That would benefit all libguestfs users.
