I concur. Seriously it's job is to act as a repository of PDF files. It does that it does that well. It doesn't not need a fancy new frontend that changes again in 18 months because "circles are in" it doesn't need to move to a "distributed load balanced fault tolerant web scale platform solution" (that costs about 2x in maintenance and engineering time as it currently does). It doesn't need to do anything of these things. It needs to serve documents and thats it. If there are problems with load they can always throw it behind a CDN since all of their contentt is largely static it fits nicely into the use case CDNs were developed to solve. Please don't change things.
