I feel the same as you. Maybe parenthesze is mainly intended to use for top level expressions, not for nested sub expressions.

I haven't looked at the issue (on my phone) but this is probably something that needs solving in the case formatting or we should use in_parentheses_only_softline_break in the if expression formatting

[charliermarsh]

Let me try in_parentheses_only_softline_break, that's interesting.

Ok this now looks right...
