Zsh and Fish’s simple but clever trick for highlighting missing linefeeds

I believe you are misunderstanding. The feature ensures that your (empty) prompt is printed at the start of a line, even if the preceding command's output doesn't end with a newline.

Start up fish and run `echo -n foo` to see `foo⏎` in your terminal.

My understanding is that the ⏎ character (and some whitespace) is printed unconditionally, but is overwritten by my prompt if the previous command ended with a newline.

If there is no prompt to overwrite the ⏎, why can I not see it?

That would actually not be OK because we can't count on the prompt to overwrite n characters, and the resulting cruft would give you an incorrect representation of the output if you captured a snapshot of the terminal state (or tried to copy and select). Fish clears the line itself after finding itself at col 0 of the correct row. See my other response for more.
