Some professional coauthors will probably die but will continue to have their names placed on new publications several years posthumously. The submitting author may forget that they are long dead, buried among dozens of automatically listed co-authors.
That seems to be a falsibiable prediction. It might also be a good tool to shame wrong-doers.
In theory yes but in practice it's hard to untangle from papers where someone was a proper, real coauthor or contributor but died before publication.
John Ioannidis has written a very insightful and entertaining article about the current state of the movement which calls itself "Evidence-Based Medicine". The paper is available ahead of print at http://www.jclinepi.com/article/S0895-4356(16)00147-5/pdf.
As far as I can tell there is currently no paywall, that may change later, send me an e-mail if you are unable to access it.

(Full disclosure: John Ioannidis is a co-director of the Meta-Research Innovation Center at Stanford (METRICS), where I am an employee. I am posting this not in an effort to promote METRICS, but because I believe the links will be of interest to the community)
