Most of the characters that were written out chose to leave as opposed to predesignsted red shirts. Naturally people who chose to leave in the first place would be harder to get back. Heck, Jill Wagner (Kate) didn't know she was going to die until they filmed it! Hayley Webb, if I recall correctly, didn't know she was the drachma until they filmed the reveal.
