By default syslog writes synchronously... however many configurations
have some files marked to write asynchronously. Does "data=journal"
buy anything over synchronous writes?

Synchronous writes are probably more useful still.

There is already a massive amount of data written to the log (profile
how much IO there is to a log during a large "rm -rf" or something),
making this worse for a small number of corner-cases where alternative
solutions exist doesn't seem entirely useful as-is.
