I haven't used black batting recently but have used it with Amish style quilts with good luck. I have made a couple of quilts recently with darker backgrounds (navy, forest green, black) and wish I had used black batting. I quilt using my domestic machine and usually the batting hangs over the edges until I trim it up when I'm done. The lighter batting rubs off on the darker fabric and it takes some work with a lint roller to get the fuzzies off.

I like to use black batting with a black background because the regular cotton batting leaves fuzz on quilt top, however I recently did one with a polyester batting and had no problem.

I never use black batting and use lots of black in my quilts. But I have never had an issue with the batting bearding out the stitching holes either.

I had a quilt that had some very white blocks. I wanted to tone down the starkness of the white so I used Hobbs Black 80/20 batting. I can hardly tell that it is any difference.

I just made a quilt with a large area of black background in which my longarmer did some beautiful quilting with multicolored thread. The judge said she noticed some bearding and it would have been better with a black batt.
She gave the quilt 4th place, which doesn't get a ribbon.

Way back when, the cotton came right from the fields and was never black and I have never seen old quilts with a problem with the white cotton used for the batting. I have never used black with my dark quilts and you would never know by looking at them what color the batting is.
