title-tag support

[jhmonroe]

Hello! As I optimize a site built using Frost I've encountered something interesting:

The SEO Framework plugin tells me: "The current theme doesn't support a feature that allows predictable output of titles. Consider installing Title Fix when you notice the title output in the browser-tab isn't as you have configured."

To avoid using more plugins, I looked into how it could be added manually (like via Functions) and researched
add_theme_support( 'title-tag' );
Ref: https://developer.wordpress.org/reference/functions/add_theme_support/

When I dig into the Wordpress documentation I see this particular theme_support has been around a while but is optional for themes to include as they see fit.

Is there a reason Frost chose not to include? (for that matter, it seems like a best-practice that core should do!)
Just avoiding overloading with extra PHP? Do you leave it out cause you assume most people use bloated SEO plugins that handle it?

Not sure if this is an oversight or intentional!

Thank you! Love Frost! :-)
