IIRC Helm already uses that approach?

Then my question will be... what's the advantage/difference from the
user point of view compared with putting the completions in the
minibuffer like icomplete/fido/ivy/ido do?

I mean, in general fido/icomplete/ivy work fine and comfortable. The
only difference with zsh in general will be the tabular vs vertical
view... but that can be implemented in icomplete more or less easily if
you really want to...

As I said... whats the practical benefit?
