A jurisdiction
can't just do something, that's the whole problem. The moment a dollar needs to be spent, a resource committed, whatever. It becomes a procurement problem.
Further to that there's nothing stopping a supplier from either claiming integration with another product is unfair and prejudices the competition or simply importing the data into their proprietary system and leaving the FOSS solution as some vestigial object hanging on the side.
I'm not joking when I say the system is absolutely beyond fucked with no obvious solutions. Most of it is so mundane and boring you won't ever here about it but ask any public service employee about their experiences in trying to get absolutely anything, from pens to planes to platforms the stories are all the same and many have tragic comedies of when the whole thing went wrong.
