Too weird for the UK market?

Two things I used to buy in France a lot for my breakfast baguettes were Bonne Maman Confiture de lait, and Confiture de châtaignes (à la vanille). I know Tesco has been selling the basic Bonne Maman jams - blueberry, strawberry, apricot for years but these two never seem to have made it over here. Do the importers just think they are too weird to inflict on the UK market? It is a shame.

Given Thomas has a bit of work on in France at the moment, I'll definitely be requesting the odd jar of 'Vanilla chestnut jam' and 'Milk jam' every time he's over!
