As of Oreo, Google is requiring that kernel modules be used whenever possible and that their location be in /vendor. With Lineage 15.1, devices without a separate /vendor partition will use /system/vendor, which symlinked to /vendor. To make this more flexible and future proof, allow developers to specify where each module needs to go by setting the path in the modules folder. If a module needs to go to /system/vendor/lib/modules, then the module should be placed in modules/system/vendor/lib/modules. Contexts and permissions will still be updated automatically.
