My understanding was nearly everything that wasn't digitized internally by around 2013ish was with the Archives and in their remit to digitize as of was already with them anyway. Everything after that is all electronic so it can fill out the Development Clearinghouse (DEC). It's a whole lofty academic library aspiration, except that the DEC is a black hole because the search function sucks. Sucked. It's gone now.
Also, let's not divulge too much personal info in public by asking the right questions, OK? It'll be worth it.
Is USAID large enough that, being co-located with another large agency in 99% of its overseas locations, and working closely with that agency which manages numerous annexes with scifs around DC, that it should warrant its OWN classified system? Can you find any documents supporting that?
Is there already a well-established practice and policies of formal reporting from USAID using that other agency's system for unclassified documents?

What is the name of the classified system that other large agency, large enough to be a department, uses? Hint: it's a basic portmanteau in the document above.
Is that the same name as is found in this public document as showing that a small agency with only a few hundred or maaaaybe a thousand staff with S or higher clearances, producing very few classified documents per year per this same document, might be using? https://oig.usaid.gov/sites/default/files/2018-06/9-000-16-001-p_0.pdf
Anyone who knows about this stuff in detail has zero feelings about shredding documents because they had to do that anyway to clean out their desks over the last month.
What you missed here is that the underappreciated aspect is energy density plus portability. That's it.
If you've never been in a taxi in Africa where some guy has 20 gallons of gas in plastic bags and old cooking oil bottles to drive out to a moto driver 100 miles from any sort of infrastructure at all, then I can see how you might not understand viscerally understand this.
There is nothing else to replace fossil fuels at that level of both portability and energy density. We need more work, more innovation, and more development not for people on the grid, but to get the people OFF the grid away from fossil fuels.
