FWIW, I'd love to see CL devs chiming in on whether this is a headliner or not. The approach of shipping the *shortest slot we can achieve without giving up (geographical) decentralization* is very appealing to me. I just was under the impression that any slot time change (including making it longer) would be a headliner-type PR both in implementation and scope. If this assessment is incorrect I'm happy to support this data-driven EIP alongside another headliner. A commitment to this EIP is also very simple as long as we don't commit to timelines.
