Hey MiqViq,
It explicitly skips nopkg (or AppleUpdateMetadata), so no. I bet there's a bunch of use cases out there for easy access to things we don't mind being publicly accessible, though, like 'view (your own|arbitrary) manifest' (assuming that's not sensitive in some way).
With flask only really requiring two files to be customized(there's been more text in this thread so far than there are lines of code in the project...), it would be semi-trivial(if you're already somewhat python-savvy) to:
1. modify the moscargo.html file to update the table column header, and
2. have the code explicitly only provide links for the items you're interested in - in this case, the link item in the dictionary being returned for each row in the table displayed could potentially be the pkginfo file viewable as a direct link, apache/nginx would handle the file type like normal ugly xml.
Not sure how you may want to further parse/transform/serve that data in the webpage view/interface. Being more design and web tech savvy(Margarita uses a fair serving of javascript to give a great experience when modifying your reposado config) than me would of course help with delivering your feature.
Hope that clarifies/points you in the right direction!
