Because it would then violate a system invariant that all commits are
descendants of the root commit.
You can model a git commit graph as a pathway through multidimensional
space of all possible commit trees. From that perspective it makes
sense that every pathway starts at the origin point of the
multidimensional space, which is conceptually the same as the proposed
root commit.
Anyway, I am not saying it should change, just that from some point of
views it makes a lot of sense.
