Injection means you can modify an existing query. The example are not SQL injections, they are full queries.

HTTP is not just for the web. In fact, the vast majority of HTTP trafic doesn't involve the browser at all.

The examples are realistic and useful. E.g., Clickhouse uses POST methods for queries, and a ridiculous `&readonly=2` parameter to differentiate modifying queries from readonly SELECT queries.

This is only a proposal for a new HTTP verb. How you use it (and how you interpret is) is completely up to you.

I don't see any sql injection in samples
