I agree entirely, and I am quite happy with CW, but you never know.
The other point to note, and this will probably only be ratified by a fellow Kosher-meal diner, is that the Kosher-meal tends to be a little, well, terrible. Therefore, if I can ensure Mrs M will be able to dine on a nicer option (CW), then I can save myself the hassle.
Additionally, I have been advised by FT members, that the Kosher meal is not served on the MCT-LHR routing (departure is at 00:01) so it is purely for the Outbound that she would need it.
