WP_Theme: Unused private method _check_headers_property_has_correct_type()

[marian1]

WP_Theme::_check_headers_property_has_correct_type() is a private static method that is defined but not called anywhere. It was introduced in WordPress 6.3.2 and was not used even at the time of introduction. Because the method is private, it cannot be used by plugins or themes, and removing it would not raise backwards-compatibility concerns.

This was introduced in Changeset 56835 / ​https://github.com/WordPress/wordpress-develop/commit/ed821528ee82a71078a491dfdbc30dfc8f7d7170 by @aaronjorbin.

Aaron, do you know the reason this was added? Also, would it make sense to remove it if it’s no longer needed? It looks like the function is also missing documentation.

The related PR #10839 is approved. I think it just needs a final review by the owner (@jorbin) to close it. I'll ping him about it.

@jorbin The PR has been approved. Do you think we'll be able to close this ticket in time for WP 7.0 RC1 (in ~1 week)?
