Comment (by jessecurry):

 Thank you for the detailed reply. Apologies for the duplicate issue.

 In order to have a somewhat working customizer we've been looking into a
 way to load customizer data for only the current page instead of loading
 everything, we realize this would prevent editing other pages during a
 customizer session, but this would allow us to continue working with the
 site.

 One of my coworkers was able to hardcode a page ID which allowed us to
 rapidly enter the customizer and edit that page, but he was unable to
 figure out a way to dynamically pull the page ID as it's not available to
 $wp_customize and the method get_current_screen() is not in scope at the
 time.

 It looks like some larger changes are in the pipeline, but we were hoping
 this hack might allow us to continue working with the site, any insight
 would be appreciated.
