Your examples below aren't really inconsistent. The rationales are
inconsistent, but they both appear to prefer explicit pointer arithmetic
over array notation.

Can you provide citations? Those rationales are so far out there that I'm
rather skeptical of what you're saying.

The general consensus is that array notation is perfectly okay, particularly
when you're dealing with arrays.
