Can someone tell me how, or if it's possible, to send street centerline updates to Bing for inclusion in their base maps.

The only other method is to Dim the BaseMaps
With Bing Maps API v6 it seems to be a bug that has not be update or investigated.
Though I note your not looking for alternatives but it would make sense to upgrade to Bing Maps v7 - Bing Maps v6 will be depreciated at some point in the future.
If you would be willing to update to V7 of Bing Maps API then you can use the GeoRSS support with SSL. using https://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0&s=1

Unless anything has changed in the past couple years, all proposed updates have to be submitted as a feedback/request to Bing.
If you go to https://connect.microsoft.com/bingmaps/Feedback you can propose changes.
You can also go to http://bing.com/maps and in the lower left corner you'll see a link called "Feedback." Click this, and a feedback box will pop up. If you say you want to "make a suggestion" it will refer you to the Microsoft Connect site above. You could, I suppose, report it as a problem (if your proposed change is actually a fix to a problem rather than a suggestion).
