The IRS accepts efilings in a prescribed format so that isnt a danger. If you look at a tax transcript produced from efiling vs a paper return, there is no material difference besides the fields related to how they were submitted.
I have no idea how I'd go about looking at an efiling. Does it essentially send a PDF export or does it hit an API and provide the data in a specified format? I could see how it would make sense for a giant government agency to want the equivalent of a PDF to hand off to humans so that it's "just like everything else".
