I saw similar approach in https://github.com/logfellow/logstash-logback-encoder for `logger.debug("Lazy logging {}", () -> "called");`.

They introduced special type they detect to support structured logging in Logback without waiting for v1.3.0 to become stable:

https://github.com/logfellow/logstash-logback-encoder/blob/main/src/main/java/net/logstash/logback/argument/StructuredArguments.java

like `logger.info("log message {}", keyValue("name", "value"));` 

With lambda & Supplier it is almost the same except we miss the name. `StructuredArguments` is known only to `logstash-logback-encoder` though.
