Feature request: add safe semantic HTML tags to default whitelist

[aviflax]

Including, but not necessarily limited to:

• address
• article
• aside
• footer
• header
• main
• section

and maybe nav?

I don’t know if I need to make the case for the value and safety of these tags? Personally I just really ❤️ semantic markup, it makes my self happy. But if anyone asks “why” I’ll dig up some good links to make the case.

Thanks!
