I'm eagerly awaiting for employers to start offering BTC DCA match instead of the 401k match.
Fiat math has some solid nominal savings

But comparing it against opportunity cost of stacking non-custodial BTC for the long-term... I can't see a Bitcoiner who wouldn't prefer the btc stack match even if ~50% smaller.
As you're pointing out, maybe better to setup something like that for your family/community endownment than waiting for the companies and regulators to start offering this.
