Found stuff using gcfscape

So I opened Gcfscape, and found a lot of interesting things. Some were also in the soundscape browser.
Hope some of you can explain what some of this are and how they got into the official game files.

Inside the moonbase files, there is a folder called "Mercury". It doesn't contain anything interesting, but it's name makes me wonder, if asteroid (which is technically "moon") is in beta, what is, or was, in alpha?
And when you think about it, there were the original 2 teaser posters, that are hinting for an upcoming update. One blue with a space station drawn on it (most likely asteroid) and the other was red, with a pyro on it between cliffs. That one might be Mercury?

The mvm maps are referred to in different names then in-game: mvm_manhattan is mvm_warehouse, mvm_decoy is mvm_cactusV, mvm_coaltown is mvm_deathpit.
Also plr_pipeline is chariots, soho is kong_king and foundry is harbour.

There's a folder called "tropics". It has nothing interesting inside.

There are a boatload of unused textures too if you go scrolling through them. Most of it boring stuff that you wouldn't use anyway, like earlier attempts at making gravel.

I actually did just that, and found plenty of stuff the tf team scrapped, for good reasons
