Hammond has his issues but the Sombra rework massively helped him in that matchup. It went from hard counter to soft counter because she just doesn’t do that much damage to him and he can easily catch her and kill her now.

Honestly it’s not much of a reach

Personally I just see it as a polite handshake kind of end of the game acknowledgement. Like hey we all played, we all tried, it’s over now, good game. If you play little league/recreational sports as a kid they make you do this at the end of every game so I think for a lot of people it’s ingrained politeness. Maybe sometimes it’s snarky, but almost anything else you could say is way more snarky imo. Bg, complaining about team, EZ, __ diff etc. are all the actual snarky ways to end your interaction with the other players.
