The taste or lack thereof depends entirely on what you’re used to. I drink semi-skimmed 1.5% milk; 0% milk tastes really bland and ~3% milk is way too sweet and rich-tasting. But IME it doesn’t take long for your taste to adjust to either lower or higher fat content. Anyway, to me it makes perfect sense to separate the cream for other uses (what would be the alternative of selling the skimmed milk? Just throwing it away?)
