Depends. When odf would be the standard maybe, but it isn't. Standard is microsoft office, and libre office is not 100% compatible. But you will still have to deal with lots of microsoft documents, from all the other agencies, ordinary people, companies, ..
Meaning, when Munichs government tried to switch to oss a few years ago, they did indeed lost a lot of time with broken documents, templates, layouts etc. so they ultimately switched back (direct microsoft lobbying with even Bill Gates getting personally involved might have played a role, too).
So I am all for an open standard, but this easier said, than done.
