I am using H7's HAL library to drive the USB that enables DMA, and there are many exceptions, such as errors in DATA0 and DATA1 packets. Does ST have any plans to detect or repair this?

Why ST would be concerned?

These errors may be caused by your hardware/board components or firmware code.

I think part of the library agreement is you use it, you own it.

With the H7, DMA and USB, you'd going to have to root-cause any issues and properly manage any cache coherency issues.
