The HTML5 working group doesn’t do PR. This became evident last year in the negative blog posts after Ian Hickson (lead editor) set 2022 as the target date for a final proposed recommendation. Unfortunately, this was misenterpreted as the date HTML5 would be ready for use, which isn’t true at all. Web specifications have a notoriously slow moving approval process, where drafts are proposed and discussed over many years. However, as CSS2.1 has shown, the technology can be used well before final approval is reached.
