Observe there's quite some of nesting. While that's somewhat cumbersome
in JSON, it's a lot worse with dotted keys, because there nesting means
repeated key prefixes. I could give much worse examples, actually.
This is true, but even without the repeated keys (e.g. in a syntax that
would use brackets), it would still be unnecessarily verbose and
probably hard to remember:
id=bar,backend={type=file,data={out=/tmp/bar.log}}
With shells like bash, that would need quoting to avoid unintended brace
expansions. It is not the end of the world to require shell quoting
(and passing JSON on the command line definitely needs it), but a syntax
that avoids shell quoting is marginally easier to type and reason about.
