Brevity doesn’t matter. Neither does length.
What matters is whether the work you are asking your readers to do to understand your point is commensurate with the amount of work your readers are willing and able to do.
If brevity actually mattered, we’d just say wu (無) and go on with our lives.
If length were actually taboo, people would have dropped Proust, the Mahabharata, and many more a long time ago.
