Recaptcha in China

My customers from China couldn’t see the captcha because domain google.com is blocked by Great China Firewall. Fortuntly, Goole gives us the solution: replace <script src=”https://www.google.com/recaptcha/api.js&#8221; async defer></script> with <script src=”https://www.recaptcha.net/recaptcha/api.js&#8221; async defer></script> and other links google.com to recaptcha.net.
(see https://developers.google.com/recaptcha/docs/faq#can-i-use-recaptcha-globally)

So I patched the plugin and this solve the problem. But it will be a good idea to place new domain into the plugin nativly so I don’t have to patch it after next update.
Thanks
