New command Identifier! [hitbyitem=???]

I've been thinking and i think this would be great. Ever wanted to detect if someone is hit by a specific item? Well if they add this it would do just that. Here is an example. vvvvv

(Repeating Command block)

/tag @a[hitbyitem=stick] add Hit                      (change "stick" with any item)

(A Different Command block that activates when ^^^ is)

/title @a[tag=Hit] title You got hit!

I think this is a great concept and it saves having to make a behaviour pack for it.

When someone is hit the commands register it for 2-3 seconds
