The difference with another proposal
(https://lore.kernel.org/patchwork/cover/888071/) is that xattrs can be
included in an image without changing the image format, as opposed to
defining a new one. As seen from the discussion, if a new format has to be
defined, it should fix the issues of the existing format, which requires
more time.

So you've explicitly chosen _not_ to address Y2038 while you're there.

Can you be more specific?

Right, this patch set avoids incrementing the CPIO magic number and
the resulting changes required (eg. increasing the timestamp field
size), by including a file with the security xattrs in the CPIO.  In
either case, including the security xattrs in the initramfs header or
as a separate file, the initramfs, itself, needs to be signed.
