yes. Because you have a board, and  a new (e.g.) boot block, which you
have been sent via email from a company that is supporting your
platform, and can not for whatever
reason recreate the payload. You may have even lost the source to it.
This happens.

Sure.

We don't care about ELF section names. With the current setup, one can not
mkdir xyz
cd xyz
lar -x /tmp/file.lar
lar -c /tmp/file2.lar *

because the lar -x loses all the lar headers.

This is not a huge concern to me, but the concern has been raised, it
is not unrealistic, so it might be worth while to support it :-)
