`ACT.Google.DM.NCR.user.js` error redirecting subdomain

[ACTCD]

https://developer.chrome.google.cn/ is redirecting to https://developer.chrome.google.com/ (NXDOMAIN)

The actual common domain name is: https://developer.chrome.com/

I'm not sure there are many similar situations out there.

In addition, except for the following domains, it seems that most country domain names themselves have 301 redirected to google.com:

• www.google.cn
• www.google.com.hk

I'm not sure if this script still needs to be maintained. Maybe it's time to deprecate it?
