I can see this backfiring if someone requests data in some ancient and obscure format just to be annoying.
Data needs to be provided in a reasonable and usable format; that imposes some responsibility on both the provider and the requester.

You can't ask a state agency to do an unreasonable amount of work to generate the data you ask for & in the future I imagine that threshold will apply to the choice of data format just as it currently does to collecting the data itself.
