It looks like SharedArrayBuffer was released in July 2017 in Chrome and August 2017 in Firefox [1], so I think it's new enough that almost any non-internal website using it would need a fallback anyway. So my impression is it's not quite as nuclear as other web technologies being disabled, but still pretty bad. I personally used it for a experimental hackathon project in April (in Chrome Canary, behind a flag), and I believe it was necessary for one of the aspects of the project, so it's a shame to see it disabled, but my impression is it's more "future web tech" than "the way the web works today".
