Current behavior

The route is passing this restriction relation, but still turning to the left. This shouldn't happen.

Expected behavior

The route should go straight as per the restriction

This is an artifact of routing without any avoidables using CH, which doesn't take these restrictions into account.

Currently, CH is still needed for fast matrix (RPHAST).
The mid-term plan would be to finish up Core-Matrix and then drop/disable (support for) CH/RPHAST.
