You're not the only one that isn't following the inference/point here.
What would be an example of a real-life application of array usage that
would be rendered faulty/unstable due to this limitation?

I don't understand. Is this supposed to indicate that PHP is somehow
inefficient at storing array elements?
"a single integer value stored within an PHP array uses 68 bytes: 16
bytes for value structure (zval), 36 bytes for hash bucket, and 2*8 =
16 bytes for memory allocation headers."
That sounds fairly reasonable to me.
Note that each element does not incur a hash bucket. The bucket holds
a list. The blogger just wasn't smart enough to insert enough elements
to see elements hash to the same bucket.
