Accepting this proposal as currently written would also involve the acceptance of five new individuals as Apache committers. Based on where the HiveMind repo currently is/was, that implies giving five unknowns (to me, anyway) access to Jakarta Commons as a whole. I'm not so sure I'd be willing to sign up for that.
