Well, for one, because it does not always work, see e.g. the examples
and links here:

Because if you refer to a hundred different columns in your plots, then
you'll need to add all of them to globalVariables(), and this is error prone
and cumbersome to update. If you only refer a handful of columns, then sure,
this will work as well.
