Sure, but, perhaps alignment should be seen as build into the specification in
order to ensure that 95% of the files written are aligned, whilst
implementations should still be able to deal with unaligned data.

If I'm not mistaking, on most processors there is a gain from aligning of data,
whilst things still work if data is not aligned. Thus, it pays to build
alignment into the specification design, whilst implementation would normally
not have any trouble dealing with misaligned files (except that they'll be a bit
slower doing so and only gain full speed benefits when data is aligned).

Or am I missing something.?
