Of course there are border cases which should be handled gracefully.
However, we already have a precendence, namely the handling of ties:

   <c e> ~ <c e>    % both notes get a tie
   <c~ > <c e>      % only the `c' gets a tie

There is an additional obstacle: If you do

  \relative c {
    <<c g'' d''>>
  }

you get three staves with single notes instead of a chord...
