As a "social experiment", I wonder if you would be as receptive to these things if it was you who let the top grow too much. This is one of the hardest lessons to teach, learn, or understand.
I think it would be harder to accept it if it was you, either way, the fact that it is recognized is huge.
Due to that top vigour, I wouldn't be afraid to cut it down this branch, and regrow it out to a little better tapered version of what is already there. It also has good branches to close the large, yet rear, wound.
These pics are way better.
I think letting all that top grow strong, until that lead is quite thick, then cut it back and the old top off at once, to get as many trunk buds to pop as possible, so your swap over to newer branches may be aided of necessary.
As a rule, I would always remove more from the top, almost continually restarting an apex, at least until the bottom is very well defined. 90% of the top, then 70%, down in proper increments to almost leaving the bottoms alone.
This can be adjusted to what top vigor actually is.
