re: Now that it's made the Beeb
It's for "real". But WE were chattering about it here months ago. So ahead of the curve. ;-)
BUT what about all the other ice lakes? This is not the only one by any means, it's just the best resolved one so far. At least one has been seen from Earth for generations: Korolev at 73º N. Flyover Animation

But Korolev is just the most spectacular of the type. There are probably dozens of polar region craters showing "ice lake" deposits, and there may be many hundreds of other craters with similar deposits -- cf Acidalia.
What would be the upshot of such a significant quantity of surface ice?
