This was always the case. The university system (ignoring research and other functions, since that's mostly decoupled from the type of class in TFA) serves a dual purpose as a teaching system and a credentialing system. How does grading homework (different from correcting homework -- I'll bend over backward to help students understand the material better, and learning from your struggles and mistakes is one of the best ways to make that happen) benefit either?

- There's the paternalistic argument that the adults we send to college aren't real adults and need carrots and sticks to learn properly. Making homework part of the grade helps them help themselves. This is a value judgement on what's more important (squeezing knowledge into people at any cost vs giving people agency and accountability), but I have suggestions as to exactly where people can stuff that argument. IMO, letting fully fledged adults limp through the system without the motivation or wherewithal to do a little hard work in their own self interest isn't doing them any favours.

- On the credentialing side of things, ongoing grading from something like homework helps smooth over the effects of a bad day of sleep or test anxiety. I'm sympathetic to the argument, but I think there are tools which are more accurate and less work for the students and the teachers. Start the semester with an ungraded (corrected if students want to take advantage of it, but not affecting their final grade) take-home test of the background knowledge expected for the course. This lets students decide if they're ready or should take an earlier course instead, do some selected reading on weak points during an otherwise relatively light workload in the semester, and learn the teacher's testing and grading style so that there's less anxiety leading up to a real test. Your grade in the course reflects your best demonstrated mastery on the final, which is arguably closer to what people expect from the credentialing aspect of things; nobody cares how well you executed epsilon-delta proofs during the week you studied them, they care whether you're ready for the next course or ultimate job using that skill. Allow a makeup/retake exam (new questions), maybe two, and take the maximum score. To the extent that your test has any noise, this inflates the overall score, but it mitigates the effect of a single bad day, anxiety, etc, and gives you an easy framework for handling legitimate life events. Still assign homework. Still correct it for students who want feedback. Don't let it influence the grade.

The primary purposes of research universities is research. You can't ignore the primary purpose of the institution. To the extent teaching has fallen by the wayside it's because universities are research institutions first and teach and credential on the side.
