Oh, I'm one of the humans who prefers one line per entry - at least
for short entries. I'm not against changing the log format. I'm just
not sure if you can put a stack trace on one line and keep it
readable.

I wouldn't like to have a binary file format that I need a special
program to read, or that is incompatible with standard tools like
grep, tail, etc.
