I agree with Fox’s point on needing to check incumbents potentially clinging to power, and I think having Core Contributors involved in the election process is a good solution.
I would like to propose that they not be the sole electors, however, as I am worried about the potential for corporate capture down the line. We’ve seen a lot of concerns about Blockstream’s influence over Bitcoin Core over the years, and Bitmain nearly successfully killed SegWit in order to preserve their ASICboost advantage.
Instead, perhaps the electors could be comprised of both the Core Contributors and the council. I’m not sure what if any balance would be appropriate here. Long term I’d expect (hope?) that Core Contributors significantly outnumber the council.
Article IV touches on conduct and yielding seats to more qualified individuals - I would also like to suggest including some impeachment/removal clause in the event of, for example, evidence of illegal/unethical activity and prolonged unexplained absences.
