Hi, noticed that you standardize many phone numbers in China to
+86 123 4567 8900 in a format such as https://www.openstreetmap.org/node/5576334930/history
But I have doubts about this, because [E.123](https://en.wikipedia.org/wiki/E.123) only adds the international telephone area code in front when expressing an international telephone number, only in domestic there isn't necessary to add area code when dialling.

In fact, if you use a Mainland of China mobile phone number to make a call in mainland China, you will not be able to get through by dialing +86. I don't think it is necessary to emphasize this point.

Of course, this is just my personal opinion on how to standardize the recording of phone numbers. I also hope to hear the opinions of you and other editors, as well as your discussions in other countries or regions.
