For 0.10.20, I'll use the version with the thin horizontal exit platform. It's horizontally shorter than the 0.10.19 Eye of the Needle. Forestidia covered the fix with Proxima's 2017 solution.
Reason: geoo worries about ease of execution for 8/10, and mobius approved this thinner platform.
Proxima, if you eventually disagree, we can change it later.
