I am assuming that a professional can do their job, yes. The whole XHTML thing where allegedly it never caught on because people can't write valid markup has never made sense to me. They're able to get typescript to compile now, right? If a dev couldn't write react code that compiles, we would fire them, right? We have tools to check that your document parses and conforms a schema. We've had them for 20 years. It's easy enough to have that be part of your CI pipeline. The tooling is 1000x simpler than modern frameworks, and the thing that was allegedly difficult was that if you enabled conformance mode (which was opt-in based on DTD and/or MIME type), you had to open and close your tags instead of just opening them. Surely any middle schooler understands when you open a parenthesis, you need to close it?
