Isn't the purpose of size_t is to be large enough to address

Correctness requires using size_t.
yes. besides, there is no such thing as "negative length", so
it's
somewhat... weird to use signed integer for length.
A length can certainly be negative. Just as a bank balance can be
negative. It's just a number.
If I have two pencils of length 10 cm and 15 cm, then the first
one is -5 cm longer than the other.
Of course any physical pencil is always of positive length, but
that doesn't mean that typeof(pencil.length) can never be
negative.
