This might be too broad of a generalization. I find a lot of cover art quite interesting, and I hope it remains prominent. I think a (dis)like for cover art might just be a personal preference.
When I listen to music on Spotify or whatever, I do still pay attention to the cover art and spend a moment to just admire it if it catches my eye.
In an abstract sense, the association of visual art with music, is, of course, a good thing that I'm sure is here to stay.
UPDATED TO ADD: Perhaps the abstract concept of "album" is what needs to go the way of the dodo.
Whether artists have enough material to justify an album-length release is a different topic.
