This proposal was intended to increase the active collator set size to 16, however:
After the runtime upgrade to Zeitgeist v0.3.6 (spec_version 40) the parachain-staking pallet (that is eventually invoked by the proposed call here) changed the function indices within the pallet. The function selector for setTotalSelected was 0x6e06 before, after the runtime upgrade setBlocksPerRound became 0x6e06 and setTotalSelected now has the function selector 0x6e04. Consequently, before the runtime upgrade this proposal was about creating a simple majority vote to invoke setTotalSelected, but after the runtime upgrade it became setBlocksPerRound.
Please reject this proposal.
