That's a specious argument IMO. The same case can be made for the pipe/vertical bar character. So I guess they have to remove that from the language too so Mac users won't be mildly inconvenienced.
You do not have to type a space though to get a pipe character. Tilde and backtick are the two characters which are hardest to write on a Swedish keyboard.
It's not difficult to type (Alt+¨ followed by a space), but you can't find it by looking at the keyboard.
