Why is the first example bad? In that specific example, I do believe the one that's BAD is more readable. We already have a rule that requires code blocks for control statements (example attached), which makes sense to me. But I'm not sure about enforcing code blocks for everything, specially for simple statements like the one you shared.

// BAD
if(condition) foo()
bar()

// GOOD
if(condition) {
  foo()
}
bar()
