The question that had to be asked :D First of all, with the current query string size, you can already send quite big queries (8kb), which should suffice for many use-cases. The introspection query, already quite huge for reference is 1kb. For the ones who need more - splitting the values into `Vary` headers is an option to further increase it. At some point - around 50kb there just is a hard limit. If you then want to send an even bigger query - we have persisted queries on our roadmap. Then you'd just send a hash.
