Sometimes, you must remember, a standard like POSIX has to codify
existing behaviour, not because it’s the best behaviour, but because
it’s the most common behaviour (or the common behaviour among products
from companies which are/were the biggest marketing heavyweights at
the time).

Because who can remember the difference between a “special” or
“regular” built-in?
