It really was buggy, with security implications. And we have no maintainers.

So the scroll-back code can't come back until we have a maintainer and
a cleaner and simpler implementation.

And no, maintaining it really doesn't mean "just get it back to the
old broken state".

So far I haven't actually seen any patches, which means that it's not
coming back.

The good news? If you have an actual text VGA console, that should
still work just fine.
