Fair enough, you deserve a longer response, and I will work on one.
However, I generally feel it has been adequately stated that revisions, boogers and all, have been made public, and multiple methods exist for capturing them - screencaps, web-scrapers, archive.org [or other archive teams] rolling through between edits; removing this edit-history does not stop edits from being archived, but it does stop the ease of use for those that would use them. In other words, you are throwing up barriers to entry for legitimate uses while not stopping other uses (the harm of which has yet to be shown).
Hence: concern trolling, an admittedly hyperbolic label.
NB: this is a preliminary version, and is probably subject to revisions. You may or may not be aware of these.
