1. Nobody sees this as a big issue.

2. As-is situation is good enough.

3. I guarantee that you will have colleagues that will accidentally add empty dirs. (I definitely have seen when they accidentally add built artefacts; dirs would be lesser issue as they would not increase repo size by much, but still)

4. Actually only first two reasons matter, but for nitpickers there would be also a bit dishonest but formally correct pointing to some doc saying that it is file or content tracker (and formally directory is not a content)
