I feel the same. PDS has an open issue about the possibility of having the original comment in their editing feature, which would allow a "prepend" operation.
Reddit pages are among the most useful for many search queries I have helped many others throughout the years. But Reddit as a company doesn't deserve this leverage. For situations one really needs to read a deleted post or comment, with some luck they can see it in http://webarchive.org/ - that's actually how I would see most posts that I needed after the June 12th blackout.
