This is smart-alecky. For example, one gets to this page by going to http://www.vatican.va, so it’s hardy likely that one thinks it’s only the website for Pentecost. The older page was familiar, which made it a bit easier to navigate than the new one, and you do have to be familiar with church jargon for some of the links. “Popes,” for example, would be a better term than “Supreme Pontiffs.” OTOH if one isn’t looking for a motu proprio, it probably doesn’t matter if one knows what a motu proprio is. The way I learned my way around the old site was by clicking things until I got what I wanted. Same here. It could be better. Address complaints or suggestions for improvement to the webmaster (whoever that is).
