Yes, all three were "one time events", however the Goobbue (like the Lightning Strikes event) was literally just a one time event, which could have just as easily occurred in the early days of A Realm Reborn instead. "Hey you guys, here's a fun quest with a reward that won't be available once the event's over!" pretty much sums up both the Goobbue and Lightning Strikes events. There will obviously be more one-time events moving forward, the rewards for these will also fall into the same category as the Goobbue mount and Lightning items.

However, it's highly unlikely at this point that 2.0-onwards will ever see a catastrophic failure leading to another overhaul resulting in another 1.0-2.0-like character transfer (Tattoos) and the Legacy Campaign (Legacy Chocobo). The intent behind these was vastly different from those behind the Goobbue or Lightning items.
