I recall DSJ arguing that one of the reasons for Lotus not progressing the turbine car further was that they didn't want Lotus-Pratt and Whitney taking points off Lotus-Ford. Not much fear of that, I would have thought! And with only the top finishing car scoring constructor points the opposite argument might hold too - two Lotuses could score points each race instead of one.
If prize money was paid out equally per point scored then it wouldn’t really matter anyway.
