I am not sure, if all these basic websites and blogs build with WordPress need something like Vue or or React framework behind it. It will be interesting to see where WordPress will be in few years if there is continuously "adding" without any "removing". Do 80% of users need this kind of framework for their "about page" and sharing buttons? Anything I install (plugin, theme) the biggest job for me is to removing extra scripts, files and junk around. Currently after some tests of alternatives to WP I ask myself, do I really need to host and manage that WP monster for simple websites? I feel that for basic website is WP too much and for something more complicated it's not enough. I see the advantage with that low barrier to entry and huge community - plugins, themes, tweaks, but WP at core does not looks so cool from my perspective. I can even say, that WP is only about that community around. Maybe this community can say to WP (code) where to move, not that WP will force them to do something.
