The situations are not really comparable.
Back on live, we had 12 characters slots per shard unless we paid extra.
Now, we have 1,000 per shard. That makes grabbing names that you 'might play some day' trivial, rather than using up valuable character slots.
Edit: Also, it was never run again because the devs said it didn't free up many names.
In this very thread, GM Impervium said: "But yes, under-leveled, unplayed characters are a huge deal, and I can guarantee a LOT of names are going to get freed up!"
