One should keep in mind that completion is not the same as narrowing.
The former expands substrings, while the latter is more like a system
for selecting an option from a list, that usually comes with some query
system.
              
Confusing these two can lead to uncomfortable edge-cases for both sides,
and sadly a lot of packages assume that completing-read is the same as a
hypothetical selecting-read.

But for someone like me who doesn't use a selecting-narrowing framework
like vertico, it suddenly means that SPC is rebound to
`minibuffer-complete-word' and entering new commands becomes *a lot* more
cumbersome.
