I think we can have and use UDAs in Phobos without yet having to create a  
guideline.  Note that there is lots of experience with attributes in other  
languages that we can draw from.  Most people here have written in at  
least one other language that uses them.

I have no problem with std.serialization using attributes, even if there  
is no "official" guide.
