Is your feature request related to a problem?

It would be much easier to develop some intresting things with events of changing entity statement, like onGround, etc.

Describe the solution you'd like.

Just create some events classes like OnGrounEvent for example, which will contains entity which statement was changed and the value of statement.

Describe alternatives you've considered.

Now coders have to create their own events for observing eventity changes its statement.
