Comment(by steven_watanabe):

 I don't think that it's safe in general to rely on the default
 implementation of has_push_back for sequences where push_back has any
 requirements on the arguments.  I guess it doesn't hurt to make them
 complete types, though, since this is a pretty minimal requirement.
