The cost, time and effort is the bankruptcy itself. Once that step is taken it would be the equivalent of omitting any other debts because the cost, time and effort it listing them.
I think maybe your hypothetical is assuming the cost/benefit of a bankruptcy purely for a student loan as opposed to multiple debts, and I am addressing my desire to see 100% of those already filing bankruptcies to list student loans, and as you will see another comment listed the statistics, it is a tiny percentage of filers who list student loans, but of those who do nearly 40% are successful.
