Keto is not a mainstream diet though. Keto requires far more knowledge, understanding and (importantly) discipline of what you are doing and what you are eating. Huel is a mainstream product with mainstream advertising and placement (ie, now in UK supermarkets). It’s design and purpose is seamless integration with an existing diet so you can have 1 meal a week or 2 meals a day, it’s upto you. You can’t operate a keto product like that.
A company has to know what its market is otherwise it confuses its customers by having too many products which would end up conflicting against each other.
Keto is best serviced by a Keto specialist company.
