Not playing well with WP core function wp_using_ext_object_cache()

Hi,
WordPress has a core function to check if persistent object cache is enabled on a site or not. It’s wp_using_ext_object_cache() Link: https://developer.wordpress.org/reference/functions/wp_using_ext_object_cache/

But the problem is that inside this plugin settings if I click on “Disable Object Cache” which flushes the object cache + removes the drop-in, but the above function still returns true.

Is something can be done to ensure the WP core function to check if a site is using persistent object cache returns correct data reliably?

Looking forward to your reply.
