What possible sort of shielding could there be?

Well, you could put a shield around each wire. In fact, they have a
word for that sort of thing -- coax. Or you could move the wires
closer together -- that wouldn't shield anything, but it would
decrease the radiation. Or twist the cables together like twisted
pair -- but that would require some sort of insulation on the wire.

All of these methods are many many many times more expensive than just
running coax or fiber alongside the power line and using that for
data.

Or is there some sort of magic, yet cheap, shielding that they could
do that I'm just not aware of?

There's conduit and to a lesser extent BX wiring in the house, but
nobody's going to change
out the romex to get this shielding. And you still have all those
unshielded portable power
cords feeding table lamps, toasters, TV sets and such...

Yes, but conduit and BX wiring will cost more than an eqivilent length
of coax or fiber ... right? I don't see any shielding as happening --
if any sort of shielding is required, it'll just be cheaper to use
something other than BPL.
