Maybe we can try to add this in M71.

We should also add the docked magnifier and switch access modulo UX review to remove them from behind flags.

commit 83a043576ee3471e2d6588d3ceb98036e7c69c94
Author: Katie D <katie@chromium.org>
Date: Thu Aug 23 02:56:47 2018

Adds Select-to-Speak to the accessibility OOBE screen behind flag.

The --enable-experimental-accessibility-features flag must be on
in order to see the STS option. This should be removed when a
launch bug is ready to go.

Accessibility OOBE screen can be too tall with feature flag.

With --enable-experimental-accessiblity-features, too many a11y tools
are included in the OOBE screen and it flows behind the button. This
makes the accessibility tools list scroll.

Oops, it's still behind the flag, re-opening.

Please add back on the a11y-testers label when ready, thanks!
