This pull requests makes the Bech32 checkbox to a P2SH segwit checkbox and makes it therefore a different kind of opt out.
Because Bech32 is standard now in Bitcoin-Qt, it shouldn't be extra mentioned IMO. Although I'm not a marketing expert I still think it is better to use this approach because I personally unchecked all check boxes where I don't know what they do (you may accidentally sign up for a spam newsletter then).
