Yes.

Correct. The script resource is generic - used for when a more specific
resource type is not available. For the developers to build a framework
to do health checking is adding (potentially) a lot of complexity where
it may not be warranted. Simply throw it back on the implementer to deal
with - the KISS principle.  :-)
