Not accurate. Conan won't do anything if no value is specified. But the compiler will use, of course, the default value.

Idem. Not accurate. You can say that when no value is specified, Conan will compute by default the same package_id corresponding to the default std of the compiler, so when you explicit the std value for the default of the compiler, the id will be the same as no specifying it.
