It's big vindication for the bouncing ball approach. On the other hand the proximity of the moon makes it much more practical to field crude designs on a more frequent basis, or to put parts in orbit and assemble them into something more ship-like.

Not really, it's only been used for a few Mars missions, and not recently. For lunar missions you don't have the benefit of aerobraking, so you have to use so much fuel to slow down already, the math doesn't work out to use airbags at the last step.
