My first thought was exactly this -- a re-invention of the original AngularJS, which aimed to combine elements of scripting with HTML. I was attracted to the original AngularJS, but not so much the later "Angular".
It's a shame as I liked a lot of Angular.js but it still lags behind in size and performance these days so it's only attractive to teams that know they're making large, heavyweight web-based software from the start.
Without an upgrade path I wondered why they didn't wait.
