It was not supported in 2.79. So, it is not a bug. It is a feature request.
Feature was thought to make change from an ortho side view to a user perspective one.
But not in the other direction.
And as is, it is normal to be archived as a ToDo.
Having its request marked as a ToDo means that developers are agreeing that is useful and should be done. It is not a dead end.
If they were disagreeing, they would have rejected your report as invalid.
Of course, each dev has an enormous ToDo list. It can take months or years before that thing that you pointed will be done.
@William replied on devtalk about where the auto-perspective option is now since User Preferences window redesign.
Unfortunately, we don’t know if he assigned the task to Dalai or Clément.
If it is currently a minor task for them or not.
I use numpad keys for views related to active selection more than for standard view.
I use viewport orbit snapping.
But I don’t like autoperspective. I prefer to keep all my views in ortho mode.
But I can understand that people using autoperspective would prefer to have it working with orbit snapping, too.
You are right to call for support from people judging it useful, to increase its priority level.
Maybe people against that could explain why they would prefer to keep current behavior.
But don’t suggest that is ill will from devs when they validate your point.
