As I understand it, email administrators have freedom to set up their own policies as to mailbox names, filters, etc. Even if an email address is syntactically correct, it doesn’t mean it cannot be rejected by system policy. If a particular service is rejecting email addresses just because they are using letters of other alphabets that might be a problem UASG would want to take part of. In the case of symbols (e.g. emojis) used in the mailbox name, what would be UASG angle here?

Emoji in Email address example is neither part of IDN nor DNS. Here it is part of mailbox name.

My idea of sharing is that Google and office365 receives email successfully from email address where mailbox contains emoji, outlook deals it just like normal email and gmail shows it dangerous.

May I quote from the 2 March 2018:

..what we agreed to is that emojis are not part of the current standard for IDN/DNS. As such it is out of scope for UASG.

Some Interesting things to note:

I am testing with Two working Valid Email Address with heart shape.
❤@data.in and ♥@data.in

( ❤ - xn--qei    and    ♥ - xn--g6h )

When I receive email from the above ID`s, In mobile devices these above hearts are shown in different red shades.
However If I send email to Gmail / Outlook, they consider this as  Spam.  Not only spam, Gmail displays the following warning. -
This message seems dangerous
The sender’s email address uses abnormal characters, which might be used to spoof real addresses. Avoid clicking links, downloading attachments, or replying to this message.

Probably, we need to discuss this too and have our views around it.
