Remakes like that happen in every game though. This has nothing to do with the Reflex team's vision, it's just random users creating the same shit on a different day (or in this case, decade. aero was released two decades ago, jesus christ that makes me feel old

).
They can't really do anything about this, and why would they, it's creating more players for the game, because a lot of new players like to play in familiar surroundings with unfamiliar gameplay elements.
In regards to aero itself, it is a map that plays out so much better in a cpma/quakeworld/reflex movement style, as it has a very narrow and quick turn centred layout. This allows the losing player to nick items and weapons by simply outmanoeuvring his opponent, where as in a vq3 environment it's just not happening because it's too slow.
Either way, I'm one of the most vocal people in the Reflex community when it comes to creating new creations. I've never been a fan of bringing in old maps in a new game.
I find the stakegun interesting, but not for 1on1. It has potential for some great teamplay in modes like ctf, because you can use to block enemy flag carriers or set up a doublejumpescape to a higher route for your flag carrier. We'll see though, the game hasn't come far enough for strategies like that to evolve just yet. (CTF isn't even implemented)
