Technically, you could dump the disc as an iso, then restore it to a disk later with the encryption intact.
Possibly not the best idea from a future access standpoint, mind!
I remember getting my first waterproof phone (Z), every port had a flap over it. The only exception was a special docking connector, that took +5v and gnd. And I thought (at the time) "that makes sense, all the other jacks probably can't be waterproof".
Then 6 months later, I was handed the Z1, complete with waterproof 3.5mm jack.
Another year later, the Z3 had a waterproof charging port too.
It definitely feels like these things are gradually possible, if the manufacturer actually wants to achieve it.
In a similar more minor vein, the Snowpeircer (tv show) sub was administered by the showrunners.
They were mostly subtle about it, but quietly removed lots of posts after a week or so that didn't fit show promo.
I'm pretty sure they've abandoned it now that the show is in limbo.
It's pretty great. Though I'm sure it's built into the price (assuming they're talking about Uniqlo).
On the other hand, being able to walk into the supermarket, fill a trolly, then walk through an archway to get rung up...That would be pretty amazing.
