This nuclide still has a HUGE excess of neutrons.

I can only assume this is confusion on the part of a science journalist, who took 'relatively' stable and indefinitely stable -- the canonical usage of the word 'stable' -- to mean the same thing.

Si-28 is the only stable nuclide with A=28; no others should be expected.
