I'm not sure I understand what you're saying? PDF isn't a machine-readable format for most kinds of data and keeping inherent court costs down is always a concern because it keeps the courts fair to the poor.
I’m saying that most jurisdictions likely already do require data to be machine-readable, but when you run into PDFs, it isn’t a document dump (which courts don’t look kindly upon), but is instead a product of mixed parts convention and motivated laziness.
