Two further options are offered for use with Adobe Photoshop and compatibility with the Adobe Color Engine (ACE). Capture One does not support Black Point Compensation (BPC). In third party applications, this is often achieved using a linear transform on individual XYZ-values, which does not preserve accurate colors. Therefore, it is necessary to disable this option where possible. Note also that Adobe Photoshop enables BPC when Perceptual rendering intent is selected regardless of other settings. Therefore, it is recommended to select Relative Colorimetric instead and disable BPC and enable Use Dither.

If the image has only colors which are included ('in gamut') in the destination color space, especially if it is a small space compared to the C1 internal space, let's say destination is sRGB, then a colorimetric e.g. relative rendering intent is suggested (by some other sites) because the colors will not be compressed as they would be by the transformations/sqeezing of the perpetual rendering intent. Highlights will be preserved very well and in-gamut colors will not be shifted.
Provided that is true, then a black point compensation feature in the export recipies would be very helpful, because shadows are often crushed with relative rendering intent, thus prohibiting making use of this intent.
Could you comment on this?
