The commenters are trying to point this out, which misses the reality that the developer probably isn't going to budge from their requirement of universal support.
That dev's rationalization also sends a signal to any commenter with the technical chops to submit a PR, that it will probably be rejected for not supporting 100% of the codecs. I have no doubt people who could do it, over the years looked at that thread and concluded it would be a waste of their time.
