We're talking about governmental document-like websites with relatively simple forms here, not your particular legacy web app, there is no excuse for not getting them right. Gov.UK did. Plain HTML, used in a straight-forward way that is very clear from the approachable documentation on, say, MDN, is already responsive, readily consumable by screen readers, and works with any backend that already exists. If you have to fix a mess left by someone else you have my sympathy - I've been there too. But the original post is appealing to people who have a choice between plain, standard-use HTML, and any alternatives. And yes, I'm all for much harsher penalties for private companies that produce inaccessible web sites/apps too.
