What are trying to comment on?  It sounds like you are describing a
problem you are experiencing with the current behavior, so I don't see
what relevance it would have to the new proposed behavior.

The "strange things" you describe are quite likely due to Lilypond's
automatic creation of voices and should likely be avoided by creating
the voices manually.  It is likely that the proposed change of behavior
will still require manual creation of voices in order to reliably keep
weird things from happening.
