I'm not sure. It's possible that the format manipulators will come in 
addition to the format in the facet, or in place of it (the facet will 
no longer contain a format string). I can't say that I have a strong 
opinion on this matter. I'm really not an I/O expert. Of course if the 
chosen way is to have both, then the manipulator format overrides the 
facet format.

It's doesn't matter. When you don't have access to the stream (as in 
lexical_cast, don't know about program_options), you can apply neither a 
facet, nor a manipulator, so there is no difference.
