I don't think this sort of thing is worth changing. I know, IntelliJ
suggests it. Unless the mutability is an issue, I'd leave it as a shorter
idiom. I wouldn't use static imports here personally.
there's also a very small cost of changes in that they create potential
merge conflicts for other changes later, so I tend to have a very low but
finite minimum bar for value of code scrubbing like this.
