"Sarah wrote this article and calls using the customizer a plus. Therefore, it is a plus."

Now that's just silly. There's a big difference between stating an opinion and purporting to state a fact.

You are right that the "The customizer is here to stay whether you or I like it." Which is why I have made no comments on Trac. I have no interest in developing it, just in disabling or ignoring it.
