Sharing from experiences of dealing with debt
The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

PPI and similar belong to the IVA in perpetuity (as long as the IP has an interest). I imagine, but you need to check, that the pensions reference is regarding potential mis-sold policies. If so it looks like the industry is beginning to latch on to other income streams to replace PPI when it's deadline expires !
My opinions are merely that .. opinions based on experience. Always seek professional advice.
