That used to be the case before I did a format change. Compression
pretty much requires a format very similar to JFFS2. The alternative
would be _huge_ complexity.

However, it would be possible to create specialized XIP segments with
the old page-aligned format. Supporting two kinds of segment format is
still simpler than supporting compression with the old format.
