I agree.

Apart from two cars that I owned as a job requirement, I have only ever had bikes as my main means of transport.
As a young man in London just starting out in the job market or even back in Uni' I soon found out that after the bike itself, the insurance the tyres and repairs, precious little money is left, and so things like economy have always been a concern for me mostly due to their practical impact on my living standards : do I buy some more food or fill up the bike??

I discovered a long time ago that specsheets and real world virtues were often poles apart, but, as always specs sheets sell and they will continue to do so because, unfortunately, motorcycling is already predominantly a hobby, certainly in the UK: after all the avaerage annual mileage of UK bikes I think was about 3-4000 miles!!

With that sort of usage, petrol is not a major expense: it is just not a priority for the guy that has just decided to buy a Gixer 1000 for Sunday blasts and track days.

What will need to happen, IMO, is that cars will need to become less of an attractive option and bikes more so.

At the moment in the UK, apart from lower road tax, fuel economy (in some cases) and the initial purchase (sometimes), everything about bikes is more expensive, incuding the lengthy means of acquring a licence. People are going to mopeds and super-scoots before they are looking at motorcycles.

Only when the above happens and the market changes will the manufacturers start looking at the specs you mentioned in your post above those of power and torque....
