Twenty Twelve theme uses title tag instead of add_theme_support( 'title-tag' )

[bplv]

Use of title tag is highly discouraged on a theme.

We can find this statement in theme review guideline

Avoid hard coding to modify content. Instead, use function parameters, filters and action hooks where appropriate. For example wp_title should be modified using a filter.

This is a must meet requirement for a theme according to theme review guidelines.

Hi @bplv, welcome to Trac! Thanks for the ticket.

It's not just Twenty Twelve, most of the older themes (Twenty Ten to Twenty Fourteen) do the same. In #34456, it was decided not to update them to avoid breaking backwards compatibility.

Newer themes (Twenty Fifteen to Twenty Seventeen) use add_theme_support( 'title-tag' ).

@SergeyBiryukov oh okay, did not know about that.

Sorry and thank you for the info :)
