This is what e.g. ivy does on M-x, and it works well in practice.

I find it much better to display candidates this way, and I think it
would be a step forward if Emacs dit this itself OOTB.

(It's also a popular choice elsewhere, try for example entering
something into the search bar on Google or DuckDuckGo.  The same
paradigm you see there is used in a lot of desktop software.)
