Ah ha! Now you're REALLY onto something MSFcoach...
In truth, there may be just a handful of us--perhaps a couple of dozen following this thread and a smattering of others surfacing in other communities--and surely our numbers are of little if any consequence to a global enterprise with hundreds of millions of customers to satisfy. But scores of people--essentially everyone who ever visited our home over the years and saw our squarely-situated kitchen-based iMac admired this capability, and none were even aware they had it on their own Macs at work and home.
Nonetheless, it's clearly a very important feature to some, and Apple prides itself in delighting its customers and empowering individuals, so hopefully someone there will see this issue for what it is--a real opportunity. Why?
Consistent with your commentary, I'm of a mind that there's a great deal more to all this than meets the eye--so to speak. Ongoing research suggests more strongly than ever that mental health and happiness is very positively influenced by repeated exposure to pleasant experiences, including memories. I'm a lifelong and constant photographer, and as I watched so many remembrances of the very best of family, friends, and life's myriad celebrations, I became convinced that this particularly contemplative presentation was having a significant impact on my wellbeing.
Again, I think Apple may have tapped into something of much greater import and potential than the casual observer might surmise. And coupled with the now ubiquitous and excellent iPhone camera, it might very well take root ... automagically.
It would be a shame and a real irony to squander such opportunity unknowingly … and seemingly so unnecessarily!
