I recalled the debate and concern some time ago and as a sufferer myself accepted the gap as a "design feature" to accomodate my Autocom lead.
I managed to snap one of the "ramp" pieces that feed the front seat clips (on the bike side) and the other side started to articulate so I took it off. I couldn't see it's purpose.
