I don't think it does either.

Agreed. But then you have to leave room somewhere for all possible
headers, which means you have to reserve part of flash for headers
only, which is something I would rather not do.

Many of the proposed changes will result in balooning cbfs code, which
I think we should avoid. I'm not even sure that arbitrary file name
lengths (which we have now) are a good idea :-)
