You will need to convince me of the appropriateness of opening these
It seems to me that are for the focus system, not for applications.
Why should an application be allowed to say "I would like component X" to
receive focus and tell it the reason is a mouse event" when in fact it
is nothing of the kind.
I would like to hear from others if they see a valid use case and that
there are no
down-sides to mis-use.
