If you read policy documents YIMBY support all sorts of housing for everyone. Generally ambivalent about inclusionary housing requirements because a) it depresses the production of market rate housing by 2.5 to 6 units per one BMR unit and 2) historically it hasn't been very effective at adding new units. Post Prop C the housing pipeline in SF dropped off a cliff.
Targeting BMR is going to be insufficient in SF anyway when 96% of the city rents units that reset to market rate when someone moves out, only thing that's going to help is a lot more new units of all shapes and sizes, hence the legislation listed above.
