Regarding the async backing, I'm struggling to understand how the reduced relay chain block time (of 6 seconds) affect parachain block times?

We have vesting schedules based on the parachain block numbers (block time of 12 seconds). Will they be affected at all?

  • one correction: Polkadot/Kusama relay chain block time is (and has been) 6 seconds.

I do think it will depend very much on how your schedule is designed. There is an existing discussion with possible solutions found on the forum thread on the Polkadot Roadmap. Found here: https://forum.polkadot.network/t/open-discussion-thread-fall-2022-roadmap-roundup/542/12
