I meant that in my terminal of choice, I have single action which does
both of these things at same time:
 - scrollback cleaning (also not leaving screen worth of emptiness in
   scrollback)
 - prompt positioning to top line

That's all. I don't appeal to bring Ctrl+Shift+K hotkey or whatever
else.

Since these cosmetic matters are inherent to vgacon I'm fine with it.

Regarding logout scrollback clearing not working for me. ncurses-6.0-rc1
which I tested it with is the latest available in Gentoo portage, please
confirm whether I need any newer version, or should I tune something
else. I'd appreciate if you also tested your patch with gentoo setup.
