@s0me0ne-unkn0wn I was under the impression that there was something pending before this PR could be merged so I've been holding off on approval, but I've just seen in the chat that you're happy for it to be merged. What were you referring to in this comment: https://github.com/paritytech/devops/issues/3261#issuecomment-2047474907 |

This is phase 2 of async backing enablement for the system parachains on the production networks.
It should be merged after polkadot-fellows/runtimes#228 is enacted. After it is released,all the system parachain collators should be upgraded, and then we can proceed with phase 3, which will enable async backing in the runtimes.UPDATE: Indeed, we don't need to wait for the runtime upgrade enactions. The lookahead collator handles the transition by itself, so we can upgrade ASAP.
Scope of changes
Here, we eliminate the dichotomy of having "generic Aura collators" for the production system parachains and "lookahead Aura collators" for the testnet system parachains. Now, all the collators are started as lookahead ones, preserving the logic of transferring from the shell node to Aura-enabled collators for the asset hubs. So, indeed, it simplifies the parachain service logic, which cannot but rejoice.
