I agree with you. As I had explained, a fake, but committed/intentional attack could be possibly used as a "change-up" to give the experienced tori/nage the ability to create waza from that type of attack. Just an "hypothetical" attempt, I guess. Personally, I would rather stick to committed attacks.
I would also feel the same frustration as you if my training partners gave only non-committed attacks. However, these type of attacks have made me aware of my own role as uke. This way, I can work towards correcting myself and provide some feedback if my partner continues to attack without intention. (or perhaps casually mentioning it to a senior or your instructor) The ukes may not even be aware of their lack of intention...
Either way, I still feel communication and positive feedback can help with those who deliver non-committed attacks.
