I think it would allow for application which are completely manageable via
some user interface. At the moment you set the auto indexing option or not.
If I could programmatically change it I could do things like stop
auto indexing, do db modifications, purge the index, re-index, enable
event indexing.

Wouldn't the other solution be more generic?
