@MikeBishop noted that if there are 0 placeholders, a client could do the pre-placeholder approach of creating a tiny hanging GET or long standing request and then hang requests off that.  Which is awful.

Hopefully that doesn't happen, but given placeholders are somewhat of an accident, some unintended consequences seem possible.
