The short answer to that is that "Size" predates the universal acceptance
of size_t. If we were making these decisions today, or anytime since the
early 2000s, we'd surely have just gone with size_t. But it wasn't a
realistic option in the 90s.

I'm not in a hurry to do "s/Size/size_t/g" because I'm afraid it'll create
a lot of merge pain for back-patching, while not actually buying anything
much concretely. I think this falls under the same policy we use for many
other stylistic details, ie make new code look like the code right around
it. But I'm fine with entirely-new files standardizing on size_t.
