And that is a problem. Do you know gh usernames or everyone in your org? I sure know most names of the people in my org but no clue about their handles… I most often depend on gh suggestions.

I know people in my org by their handles better than their names haha, guess it just depends on the culture of the place you're at.

Time to reinvent Java style reverse FQDN for user handles! IMO short username or alphanumerical ID is a must so as not to get into The Falsehoods.

We already have those, we just use forward-fqdn syntax like username@company.co.uk. Works great, widely implemented
