That's a sad reflection on how slowly people learn. I've been making this point in presentations for the many years, people have been announcing it in this newsgroup for at least the last 2 years, and the Cary Millsap paper you may be thinking of is dated March 7th 1996 and that says: (I quote):
More and more people have learned that
multiple extents bear negligible performance
impact upon all Oracle DML operations.
.......
The number of distinct extent sizes in a given
tablespace should be small; for example, only
one. If there is more than one extent size in a
tablespace, then all those extent sizes are
integral multiples or divisors of each other.
