Why is the customize_changeset_status param getting removed, again? Is this still needed?

As we are checking customize_snapshots_create_revision customize_changeset_status does not need to be removed now.

@sayedtaqui but core will (somewhat unintuitively) create a new revision every time the customize_changeset_status is supplied. Wasn't there a reason for the param to be removed? Did it have something to do with passing the date?

@westonruter Yes we wanted to auto save the date and title in editbox, but we could not do wp.customize.previewer.save() without status because the default status is publish, and we did not want to create revision each time it auto saves the date/title.

OK, so then we need to still include the logic for removing the status parameter, but then an additional change is needed right? We need to omit the request for a revision when the date and title are modified?

@westonruter I think save_post_customize_changeset would be an action and not filter?

You're right! It should be add_action here.
