Quite right. The advice is still there, in plain, unadorned incorrectness, in the performance tuning course notes for Oracle 9i (published in version 2.1 only a few weeks ago).
Oracle are also responsible for promoting the myth that getting a segment into a single extent is good for performance; that PCTINCREASE 1 is a good idea to protect against fragmentation (it causes it); that ASSM has no costs; that tuning consists of getting a good buffer cache hit ratio. You name it, they've touted it.
These days, they have TUSC to do that sort of thing for them.
