For what it's worth, I've seen the same sort of interoperability issues with all similar software. Author A wants "the latest copy of the Endnote file" but nobody's using Endnote; Author B insists on emailing PDFs as attachments and uses their email as their personal literature database; Author C has set up a Dropbox full of PDFs but nobody uses it; Author D has created a shared Google spreadsheet with links to each paper but it's always out of date; etc etc etc.
These aren't issues with any one piece of software, they're issues with coordination, as are the examples you mention.
Yes, I think that makes a lot of sense. Maybe the issues I am referring to are more to do with the general frustrations of putting together a paper with multiple authors and less to do with specific software.
