In a new build, if the house isn't going to get a gas heater (to make that 97% reduction in home gas usage) then the builder isn't going to want to bother laying a gas pipe just for the cooker. That 3% reduction comes as a saving on inconvenience, not really as a saving on carbon emissions.

Is there a tank alternative? I much prefer cooking on a gas stovetop, and would be willing to refill a tank every couple of months, the same way folks do with propane grills.

Most municipalities and or HOA's will have limits and restrictions on tanks. If they are portable tanks then it will likely be covered under whatever rules for grills already exist, but larger installs will have a different set of requirements.
