For anyone alarmed about moving towards a SPA, and potential performance impacts etc, read the comments towards the top of this link from the Vue Team Lead and proposal co-author. They address the most obvious concerns.
Thanks for the link. A lot of people went out of their way to criticise Vue which makes me wonder how the general opinion of Vue has changed in the last year.
