I somewhat agree with you Baloo but... It was no different when someone "liked" a post prior to the upgrade. If they did, you received an email notification stating that "Chris added a Like to ...." If I removed that like, which you could do, it did not send any additional notifications. It was just the initial "like" that did.

So I personally feel that if someone reacts to a post, there should at least be that initial notification that "Chris reacted to a post..." If I choose to change that reaction or remove it all together, there should not be another notification.
