Possibility of changing Rowid because of UPDATE operations

Hello All,
Do you think of any situation where Oracle would change the rowid(or move
the row that causes rowid change) under the hood in 8i/9i or even in 10g if
there are simply Update operations happen on a row?
I know that the Rowid of the row is not going to change when there is a row
chaining/migration. So, this is not an issue. And, I understand that the
Rowid would change in other situations like row is deleted/inserted, table
is exported/imported, truncated/reloaded or alter table..move and other
similar operations.
But, I am only concerned with Update operations. Even in IOT and Cluster
tables, I believe Oracle would maintain the same rowid if there is an
Update to a row.
Please let me know your thoughts/suggestions.
Ours is a DW environment and would like to use the rowids to identify
changes in the source table where there is no primary/unique key.
Thanks in advance,
Best Regards,
Prasad
