I can recall in 2007 when even having third party apps was a debatable topic. Call me fogeyish but it's inarguable that this was not really the intention of iOS, rather, we have mitigated and papered over the problem due to insane app store popularity. Macs didn't have native notifications for decades.
In other words, our priorities have drifted significantly and it may be time to holistically reevaluate this.
