It's still okay to use `<b>` and `<i>` tags in HTML5, but they don't come with inherent styles anymore.

They do. Browser style sheets define both elements, and that formatting is the expected default. I think what you mean is something like:

“It's still okay to use <b> and <i> tags in HTML5, and they don't have to be styled bold and italic respectively (although if there’s a more semantic element, use it).”
