it's going at the end of initcode instead, which is cheaper but still possible to pick up the vyper version by looking at the create tx.

Needs some QA by deploying on a public testnet with brownie or ape (preferrably both)

@fubuloubu what exactly do you want to see here? the issue i am anticipating is that the contract will not verify anyway because the bytecode will not match 0.3.9 (or any other released version of vyper)

Doesn't need to be verified, just make sure that regular and blueprint deployments work on Sepolia or something

using titanoboa, i was able to deploy test contracts with the latest commit on this PR (4394ba4) to sepolia:
carbon - 2023-06-03T001049 746

you can check that the runtime contracts don't contain the vyper signature:
https://sepolia.etherscan.io/address/0x5941ac081899ff0e9941ea4c91eb3cf6a57e2d04
https://sepolia.etherscan.io/address/0x98b2beaf877ad73e010a6ad264c88432411b1b0a

and the blueprint contract does:
https://sepolia.etherscan.io/address/0x2dbf66af9b979245710d13ac5ea79778759d1ca2

all three contain the signature in the creation traces:
https://sepolia.etherscan.io/tx/0x8ca2c12ab395df5cc1f2583fa60350078894940685b51a726d4d0f40d4a45c94
https://sepolia.etherscan.io/tx/0x12c78aefc0e4f2552339d22407c9683c58cab7d3824c07dc98b750a297531cb9

also note that a recent dashboard created to check vyper deployments in fact already uses the creation trace as opposed to the runtime signature (presumably because immutables are appended after signature in the bytecode): https://dune.com/queries/2555852/4221288
