Beta content on Valve servers

[Zvennn]

Are there still any maps, scripts or sequences from beta in the Valve depository? If yes, why valve never shared any of it, beacuse they probably know that there's a whole community behind hl2 beta.

[I love HLBeta]

1. They often reuse cut content in other games
2. They are too lazy
3. Some content has been permanently removed
