Yeah, and we gave you an answer.

sorry, but you did not give me anything other than false information.

No market for it,

You don't know that.  I don't know either for sure, but I think that it would be more market to the Pentax K lenses speedbooster than for Contax/Yashica lenses!

and someone who really really needs it can easily adapt any other SpeedBooster where the original mount (for example Canon)  has smaller flange than the K-mount. All you will then need is another glassless K-mount adapter  on top without any image quality comprise, as that second adapter on top would be glassless.

Again BS. Learn your lesson before giving instructions.

You don't know that aperture lever of Pentax K lenses may hit the adapter when you try mount Pentax K lens with EOS adapter to the speedbooster?

Many manual focus lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions (spikes, levers, other appendages) which would damage the optics and/or housing of Speed Booster™. They need to be modified before they can be safely used on Speed Booster™. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster.
