Correct. For that to work the host needs to know which parameters can be
automated and the current binding. This information needs to be
host-independent (part of the plugin state), so that it can be re-used
in various hosts across platforms.

Currently LV2 does not officially support saving parameter control bindings.

This is work in progress on the LV2 front, and co-incidentally being
pioneered by setBfree, which can already dynamically export its
control-map and bindings.

LV2 already has a vocabulary in place (http://lv2plug.in/ns/ext/patch/)
but there are no semantics that govern bindings, yet.
With recent liblilv-SVN and Ardour4-git you can already achieve this (by
copying the midnam out-of-band). Note however that this is still very
much work-in-progress.
