Just be sure that you source the correct BH-90 hydraulic hose kits, as I found there are two variants with one containing correct fittings for the new DA/Ultegra hydraulic shifters, and the older kits for R785/R685 shifters. Referencing the image below, the fitting circled in red is required for the DA ST-R9150/R9170 and Ultegra ST-R8050/R8070 shifters:

Has anyone managed to pair the R9170/R8070 series levers with banjo style brake calipers like the XT/XTR/R785, using the BH90 hose (w/crimped banjo end) using the larger connecting bolt? I believe the larger connecting bolt can be purchased using the Shimano part number: Y8RD98010.

Would like to try this once the R8070 levers are more readily available, but not sure if the larger connecting bolt will be compatible with the BH90 banjo style hose.
