I am using an item-request-proxy to collect the ingredients for a complicated building, then a script builds it when everything is there.

But I need a way to tell when the request is filled. The only way I found is to check the target every tick.

A more generic event like on_item_request_removed would be ok too, it would just take me a bit more work to verify that it was actually filled and not canceled.

Like most requests for events when items are moved around the complexity and overhead of implementing item events means it's not likely to ever happen.
