Hoping a thing is true doesn't mean it must be true :-)

No, we don't all know that because it isn't generally true, or else
you're using a loose definition of "natively." Languages differ
in what capabilities they offer "natively."
contrib/intarray implements an intarray_del_elem() function,
presumably because the core product doesn't offer that capability,
or at least didn't when the module was written. If you think it's
there just waiting to be exposed, then dig into the source code and
expose it :-)
