First, thank your very much for suggestion.

What really I have not found your email in my Gmail (in web browser), I found it
in mu4e (Emacs). Which I can't reply because I'm in China, sendmail to Gmail
SMTP server is blocked. So I'm replying you in mu4e. Don't know whether you can
receive my message.

Using unique ID is the only solution to identity contact. I already thought
about this. But integrating org-id is hard for me. Have not spent that time on
it yet. But I will, if I want to improve this org-contacts.

This proposal is useful. Do you want to contribute on it too?

After watching your proposal, I found it's indeed complex....
