We don't have a style guide against static imports, but every file which this PR touches adds the first such static import to that file. The points of Spotless is to spend less time on style. If this was a simplification I would merge it anyway because again I don't want to spend time on style, but it actually adds lines

Thank you for this batch of PRs, but I'm going to close this unmerged. Stylistic changes that we can't keep enforced are imo noise, but it's not a big deal :)

not a big deal

to create a recipe hopefully, as its noise due to IDE warnings imposed.

don't want to spend time on style

agree.

but it actually adds lines

yes, imports are blind to dev, as in contrast the context class System is not. Consider this boilerplate as lineseparator only known to be originating from the System class.

So this would actually move the overhead from statement to import area.
