The lightbulb that you're throwing away also contains all the same electronics that a larger light fixture does, just in a smaller and less thermally efficient space.
Mounting options that allow larger LED lights allow you to use lights that are more thermally efficient without sacrificing any replaceability. JIS C 8310 mounts for example.
