I agree. Pushing through TL will expose the patch to more testing and 
will make it easier to patch it. I think you are right that this is what 
we should do with this patch.

However, I'm still worried that there will be a need to manually resolve 
several conflicts with changes done in the build forest in the meantime. 
But I'm interpreting your answers as I should not worry about that.
