Yes, we will have to delete it.

As long as we are only considering good-faith mistakes, not deliberate
lies about the authorship and copyright rights, the difference between
CA and DCO is that with the former, one is _required_ to provide a
disclaimer from the employer (if that is relevant; it isn't always),
so this aspect is pretty much in the face of the contributor.  By
contrast, with DCOs one is just asked to declare that he/she has the
rights to contribute the code.  So people might, by omission, make the
mistake of not obtaining the employer's agreement, perhaps because
they are not aware of these aspects, or forget, or...
