The most recent version of the launcher includes april fools versions. I could not find 2.0 in the launcher, but I could find 15w14a (The Love and Hugs Update) and 1.RV Pre Release 1 (The Trendy Update).

Having these two versions back to the launcher should now be a problem. The first two versions download link was always available since their release, just not in the launcher. The https://launchermeta.mojang.com/mc/game/version_manifest.json was updated to include these two versions.
The case for 2.0 is a bit different. Initially, 2.0 was only available for some Minecraft creators, by the link: http://assets.minecraft.net/secretthings/do_not_open/no_seriously/please_dont_open_or_share_with_anybody/theres_nothing_to_see_here/minecraft_2point0_colour.zip
2.0 was reuploaded by emperorcaine, retweeted by Dinnerbone, http://www.mediafire.com/?9jsdbq5d85398
So, Mojang technically never reuploaded 2.0, but they may do it in the future
Technically duplicates MCL-1457; however, since 15w14a and 1.RV are present, it would make sense for 2.0 to be as well.
