That's weird, I'm using the non-spawn versions in Gun Hunt, and haven't come across any I can't pick up.

For the ammo issue, you can set the ammo keyvalue ith the table if you spawn weapons with the CreateSingleSimpleEntityFromTable(entTable) function.

Ii got it to work the same way as ThaiGrocer explains here. It seems to give double the extra ammo you input.

Here is a mutation that puts a spin on Survival mode. You start with a pistol and medkit, all initial pickups are removed. Weapons and items spawn at random points at certain intevals, with the weapons only having a few clips of ammo. It's a lot like the scavenger game mode in Battlefield 3.

This feels a lot harder than regular survival, I can hardly last 3 minutes with bots.

Current issues:
Spawns don't get deleted after a wipe. None of the game events fire after they've been placed.
No good way of removing empty weapons (no known way of reading the ammo count).

Possible improvements:
Random spawns based on nav mesh. Would need an interface to the nav mesh.

Does that mean you can punt other survivors now? Because that was the best hidden feature in L4D1.

That worked, thanks Kerry.

I noticed a related issue: If you start a lobby game, and then try to switch on cheats in-game, the same thing happens, and the convar list gets reset.

It's on purpose. They only excist as entities in Hammer, and get baked into the worldspawn entity by VBSP during compile.

I just tested it in the beta, and it works fine for me.
My script uses the format:

Weird, I've tried clearing the config, validating the cache and disabling all other addons, and it still behaves the same way.

The problem is with the Speedrun!! mutation.

Whenever I start it from a lobby with a local server, the cvars get reset to their default values.
It prints this message to the console:
FCVAR_CHEAT cvars reverted to defaults.
(Not sure if it's referring to the server or client side though)

Here's Speedrun!! as well. The bots are still really buggy, but should be competitive.
