I'm not aware of anyone working on this area and I think this is the first time it's actually been brought up. From a query/setting perspective while providing an API would clean it up a bit, I don't think it would add any additional value so I don't think anyone would really pursue it.

The interception points are complicated because they are supposed to execute quickly as they hold up processing. Defining a specific interface within ARI for doing so gets complicated due to its asynchronous nature. There's a lot of room for bad things to happen, so off-nominals would need to be covered.

If you could define how it might work/look others may be able to chime in.
