Let's distinguish "fine art" printing from "reproduction of fine art" printing-- the latter being a much more difficult pursuit with limited room for artistic subjectivity. In fact, issues of camera/scanner/observer metamerism are huge hurdles for those of us that are trying to precisely duplicate a Van Gogh. A frustration for me (and many of my colleagues) is the lack of good methods of creating input profiles. Digital cameras (even high-end units) are often are joined at the hip with manufacturer's profiles and/or "tone curves" that potentially taint further custom profiling. And once a custom profile is created there are no editing tools available (that I am aware of), to tweak those profiles. An ACR workflow may be more appropriate for what we do.

Well I never discussed contract proofing. Nor is the paper I built the
profiles for intended for that. Nor the vast majority of users of these
printers. But your point is well taken.

I don't know what others would consider acceptable. I do know that with the
3800, which produced an average deltaE 2000 of 1 (using 5202 patches), I
printed a number of what I'd consider fine art images (one group being the
LAB test file built by Bill Atkinson). I used the custom profile I built and
the canned profile that produced this deltaE of 1, the two images to my eye
are indistinguishable.
