This has been brought up on HN before, and people smarter than me identified that this view is about 10 years out of date. Yes it's a bunch of XEPs, but there are standardized "sets" apparently that include all of the things any other similar tools do. It sounds like only very niche old/minimal XMPP clients don't support encryption by default for example, and virtually all servers have supported it for many years.
