Agreed.

Is there a way we could check the notes? I looked at the patch,
and it doesn't seem like there is any kind of versioning or
identifier we could use to determine which version of the notes
we get. But perhaps we can at least do some kind of consistency
check, such as for instance comparing the size of the section
with the contents of the section header, and generate an error
if that doesn't match. The error might not be as informative,
but perhaps still good enough?
