Performance was definitely one concern, especially on earlier ARM9 devices where context switches involved cache flushes due to virtually tagged caches.
Unstructured (or really a bit semistructured -- timestamps, pid, loglevel are structured, message content is not) logs are partially to avoid having to have knowledge of the precise software running or maintaining an ever-expanding definition of log message formats to interpret the logs from an arbitrary device that's encountered. Very valuable in a large ecosystem with a huge variety of devices, software versions, etc.
The name/sizes stuff should just move to platformdata / module params / or the like. An oversight that's easily enough corrected.
