Because the figure is interesting to users as well. They will usually
not have any access to monitoring, and checking if they can load this
extra 10 GB dataset is a good use case.
This is about providing the numbers in the place where they are
needed. Of course admins can just go elsewhere to look it up (and
probably will), but I think now there's a usability gap for people who
just have SQL access.
