That's just it though, Vue & React aren't for most web sites. There is no point in pulling either in unless you are building something much more complex than where jQuery would suffice. There is no need for a technology to be "ubiquitous", just that it is going to meet the demands your application has for it.

Actually vue is so small and simple you can just drop it anywhere. Even on non JS heavy website. It's a bit like redis. Low price. Always nice to have. Very reliable.
