They are not even lookup tables, just dead weight. These off the shelf ERP products are so generic, trying to be everything for everyone, that any particular installation uses only a fraction of all the tables. Especially when you consider that sine Peoplesoft 8, you create all tables for all modules, even those that you didn't buy a license for. Granted, what are a few 100 meg in today's mega-gigabyte databases. But something in me abhors any waste, be it space or time (i.e. performance). And since I have relegated those tables already to their own "TINYTBL" tablespace with uniform 2-block extents, it is really no additional work to create it with the smalled blocksize possible.
