As always I'm putting my money on "nothing ever happens", but I do think it's probably good that we have a serious discussion on what exactly the purpose various agencies serve and refine their missions and processes to actually support them. Will it happen, probably not, but I can dream.
There's a ton of information about every agency out there, but people don't read about them. One of the benefits of government is that it allows people to ignore all the details that make modern life possible.
On the tech stack, it's like claiming that everyone should understand assembly. It's useful for some folks to know assembly, but the vast majority of folks don't care. They just want to use the stuff that's built upon it.
Why anyone would think we're going to get more transparency this time around is beyond me. President Obama started the federal Open Data initiative and Trump, almost as quickly, neutered it just short of axing it. If they cared at all about being transparent, they would have worked on the Open Data initiatives rather than shrouding everything in further secrecy.
