Nothing improved, so again, so something which is not obvious. What is
it used for? Why AFE needs topckgen for example?

Did you implement the comment or decided to keep afe?

BTW, whatever "consistency" you have in mind, it does not really matter
that much for that example. And for sure do not add incorrect code
intentionally just to fix it in next patch.
