If you can prevent this confusion in important use cases, please do.
But I really think that we need to be able to position point at the
first/last line of the window regardless of any "confusion". This is
what users who set scroll-conservatively want. They don't care how
"confused" can the display engine become. And I think you cannot
prevent confusion altogether, because with input that comes in at high
enough rate, Emacs will eventually fall behind and will be unable to
use try_scrolling. With today's code, if try_scrolling fails, we will
always recenter.
