It was the best thing we could have done!! We're almost 7 years out, so it was well before the changes, and we already had great credit, just ended up with like $30,000 in hospital bills (long story) and when we TRIED to get help from creditors they said no, nothing they could do. A year later when we decided to file for bankruptcy all of a sudden everyone wanted to "help" us, reduce debt, forgive late payments, etc.... well it was too late then!
Anyway, we were able to get a mortgage 2 years later with 2 yr fixed interest, saved and worked on credit and 2 years after that got a fixed mortgage. If you plan and are strict with yourself you can come out on the good side. Do make sure you use a good lawyer, they pay attention to YOU.. our lawyer did not, we had just a few bills we still had to pay, very little amounts, AND I spent a year "fixing" my credit because he didn't take care of all the paperwork needed and things were being reported wrong.
Good Luck
