This application is one that makes sense to run locally with the fed's implementation as a backstop and baseline (that rases the standard of minimally acceptable) -- and in this case bootstrap as well.

California has a good system that is roughly standalone while NY has one (also good) that is integrated into other NY programs. Both fan out into a network of actual humans (mix of private and public sector) that help make it work for people who for whatever reason can't use the online service. It's hard for the feds to do something like that at scale -- for example to have it integrate into other lcal programs.
