Regarding varnish cacheability of mobile API requests with a logging query param - it would probably be worth making frontend varnishes strip out all occurrences of that query param and its value from their backend requests so they're all the same to the caching instances. A generic param name that can take any value would allow for adding as many extra log values as needed, limited only by the uri log field length.
&l=mft2&l=mfstable etc. So still an edge cache change but the result is more flexible while avoiding changing the fixed field length log format across unrelated systems like text squids or image caches.
