The only dramatic size increase comes from putting the certificate in the
message. If you don't do that (as in, you don't use PKIX), then it isn't
really that large.

Not optional in the sense that it would be used as if it were signed, just
optional meaning not all assertions would have that capability. As in fact
they wouldn't. You can't just sign the assertion and magically treat it as
a reusable token. Well, you can, but those people are ignoring the
standard. Other content is also needed or you have a very lax model.
