Huh, I find precisely that behavior very difficult to use; you end up
pressing up-arrow ten times to get the first line, ten times to get the
second line, ten more times to get the third line, up to a total of a
hundred times!  And if you press it nine or eleven times instead of ten
and press "enter" before realizing it (a mistake very easily made), you
are hosed and have to start all over.

Instead of waiting for back-arrow I usually use Alt-b and Alt-f.  Or if
I have to go back 20 words, esc-20 alt-b.  This is much quicker.

(I agree that there are still bugs.  But we should correct those, not
remove the useful behavior.)
