Safari's UserAgent on Big Sur still reports 10.15.6 instead of 11.0

It has been a few months since the release of Big Sur now and it's strange that the Safari UserAgent still reports itself as 10.15.6 instead of 11.0

I see that multiple people view this as an issue but we still do not have a response from Apple on when and how this is going to be handled going forward. The webkit bug report tracking this has been marked as resolved without a real solution https://bugs.webkit.org/show_bug.cgi?id=216593

Our web page relies on the browser reporting the correct UserAgent to show relevant instructions to our users and we'd like a way not to show them the wrong information.
