While I agree with your point about the fine line between profits and customer satisfaction, the point is if you don't make the WC experts happy, they will recommend against using your products so it's essential to make sure it answer a specific need.

Look at Koolance, they refused to listen to the experts and made them with aluminium/small tubing/low flow for a long time. We recommended heavily against them and when Victor Wang came here with a GPU full cover made of aluminium, we flamed him for supporting a poor choice (he is a XIP). But then he asked if we will be ok if they made it in copper and we said yes. After a short while, he came back with copper blocks so he made Koolance listen finally. Now, we are feeling they are shifting to copper only and it's a good move.
