Optical/Hall Effect switches generally require special PCBs some part of the sensing is often surface mounted to the pcb instead of integrated into the switch housing. There is a hall effect board coming out the mechanical keyboard community called the Keystone (https://kono.store/blogs/keyboards/the-future-of-keyboards) https://kono.store/blogs/keyboards/the-future-of-keyboards)) but generally speaking such an undertaking is to big for the community in general. Requiring both full switch design (generally new switches from the community are simply tweaks to existing designs, maybe just a slight adjustment to the stem, spring, or leaf) or new layouts using existing switch footprints (generally speaking just the cherry mx footprint, but there are quite a few pcbs that will support cherry mx and old ALPs/Matias switches.
