Currently the size of a PR is determined by the amount of changes (Deletion+ Modification)
In my perception, I take on on a PR which has 120 changes in a single file much easier, as on a PR which has 120 changes across 30 files. In other words, the complexity is more interesting as the size only.
By taking a file weight into account (1 file = x changes) the labels would effectively show the complexity of the pr.
