Fair enough. But as far as I remember - correct me if I'm wrong here - these issues with 'incorrect' (or, to put it neutrally, 'undesired') font display appeared only a few firmware versions ago. Before that everything was fine in that regard. Thus there already is/was a solution for a more robust epub rendering that is not so heavily affected by variations in epub css code.
As for having to support two epub rendering engines in one firmware I can see that this requires some additional effort on KOBO's side ... on the other hand nobody forces them to do that and it is no excuse for bad or sub-par performance of either of these rendering engines.
