It can, but it might be desirable to have visible and typeable[*]
representation for unusual space characters, especially if there’s not
much nbsp awareness among those who are going to collaborate on a
document.

[*]: I mean visibility and typeability by muggles, i.e. without
relying on Emacs fontification, C-x 8 RET, or Xkb options. Otherwise:

Co-worker: (sends you a patch)

You: This space here should be non-breaking, we don’t want
prepositions hanging on the previous line when the next word gets
wrapped.

Co-worker: What's a non-breaking space?

You: (explain)

Co-worker: But how do I type one? BTW I'm on Windows.

You: (try to explain but don’t remember how to configure Windows
keyboard layouts) Here, just copy one of those already in the text.

Co-worker: But how do I tell which are which? They look exactly the same to me.
