I think there's a case where a spec could (and probably should) define
normative requirements for processing of the data that's sent to the
console, without necessarily defining exactly how it must be displayed.

The case that I think might benefit from having some processing behavior
specified follows from the fact that the first argument of some console
methods either might be a printf-like format string or it might be some
other object (maybe a normal string or maybe something else).

So I'd think you'd at least want to have something defined that specifies
1) how to detect whether the first argument is a printf-like format string
or not, and 2) if the first argument is a format string, how do you then
process the rest of the arguments.

I think that's true for the case where you're just sending objects or plain
strings to the console, but not when you're doing to format-string
thing. In order to get something unsurprising and interoperably useful for
that case, I would think some standard processing behavior for it would be
need to be explicitly specified.

Yeah, for sure
