I could be wrong, so I'll lay out my rationale and people can pick it apart if I've got a bad assumption. I think of commandline parameters as (mostly) something end users twiddle with, versus kconfig options as something system builders set up. I'd largely expect end users not to notice two ticks at boot time. I'd expect its system builders and fleet managers, who know their hardware and build their kernels optimized for it, are the ones who would want to shave off this time and go straight to the known answer. Anecdotally, at ChromeOS we had a strong preference for Kconfig options, as they were easier to compose and maintain than a loose pile of commandline arguments. The commit text doesn't go into the rationale, intended audience, or expected usage, so maybe my guesses miss the mark on what you're thinking. -Evan
