Yes, exactly. The details need to be hashed out. I'm not convinced that 99 years is right, it's long enough to ignore and then pretend to be surprised when it comes up for renewal. Perhaps 35 years and no termination clauses, to make it easier to plan around? It would allow one house for having children and one house for retirement. The improvements mechanism would likewise need iteration. I am interested to see how the various global experiments in these directions will pan out, though it looks like right now the market is betting that the 99 year leases will turn into perpetual ownership. That's unfortunate, because perpetual ownership is directly responsible for most of the largest perverse incentive problems in the real estate industry, not to mention ongoing gigantic deadweight loss.
