Actually, I suspect it works better for new users than for old ones: new
users don't yet have a clear mental model of how Emacs's completion
works so they might expect something more like what you see with a web
browser search where adding more data can completely change the
proposed completions.

In contrast old-timers may indeed "know" that there won't be any
completions further down and will never reach the second style (to some
extent, that's how I got Richard to accept `partial-completion` in the
default).

I don't regret doing it because I don't think there was any other
way to activate `partial-completion` by default, but yes it has
its downsides.
