All I can say is it matches mine. So we're at impasse I guess.
English speech varies. Even across the UK there are dozens of regional accents and dialects. Now add the many regional variations across the USA and other world Englishes. All with their own traits and habits, some more widespread than others. A deep rabbit hole with many forks then.
Common enough that I would not think it the slightest bit unnatural on hearing, or give it a second thought. I wouldn't give it a second thought reading it in a natural conversation in a book - not just in intentionally neutral business or net writing, so that's not going to be memorable. It's not an idiom I'd single out as localised to any one group or region. It would be memorable and feel odd reading if it were all that way in a novel's quoted conversation, or nearly all names with few pronouns like some telesales scripts seem to encourage.
Not as common as he/she certainly, but I dunno 1:4 or 1:8 or something. I couldn't say what proportion is names not pronouns either. FWIW My people skew international, educated, Scots and perhaps city in a part of the UK that's well north of London.
