Corse it matters. The most obvious situation is where you have two
alternative algs, one which can reliably work out what the message
is with the vast bulk of common warts you can see, and the other
which is more fragile. What the fuck is the point of mindlessly just
binning other than utterly pristine messages ? None, thats what. The
real world is about robust software, not assuming absolute perfection.

And if you just want to read the message, you may not actually give a damn.
Even for echomail, the address also doesnt actually matter a stuff either.

PE> It doesn't matter your end, it's the originator who needs to fix
PE> his software, not you.  A grunged message is a grunged message.

And it may well make considerable sense to be able to handle those
gracefully, particularly ones which only have minor blemishes. For
example a 3D SEEN-BY doesnt actually matter a stuff to an end node,
its not even used. Just plain stupid to fall flat on your face over it.
