Earlier quoted context omitted.
It’s not parent. This article is either terribly written or horribly translated. The captions in the photos don’t match what said in the text and aren’t logically consistent across the article.
I completely misread the article too (and the 'Additional context' article posted here), I think because it words things strangely but also the whole message is about change and all the examples seem to be of places where the well known spelling is already the Hepburn spelling. So the change is to official spellings that aren't used?
Yes, the whole point is that kunreishiki is not practically used so it doesn't make sense for it to continue to be the official way to romanize things and for it to continue to be taught in school when no one is using it.
