 Replying to [comment:1 dlh]:
 > I'm not sure whether there's a historical reason that the
 `WP_Customize_Manager::remove_*()` methods don't attempt to remove any
 hooks associated with the removed constructs. @westonruter sorry for the
 ping, but do you know?

 Hi! I think it's just because it's not a need that came up. I thought
 there was some ticket for it, but I couldn't find it.

 It's not great that the constructor for `WP_Customize_Setting` is calling
 `add_filter()` right away. It would be better if those filters were added
 later once they would be used. Alas.

 In any case, I suggest removing the filters. Assuming there is only a
 `sanitize_callback` you can just do:

 {{{#!php
 <?php
 remove_all_filters( 'customize_sanitize_header_footer_background_color' );
 }}}
