The feature itself doesn’t know what an editor is and what it capable of, nor should be ever rely on that. Not everyone uses the same settings and you cannot be 100% sure to expect the same string from looking at it, which was written in a different editor if we don’t warn about trailing whitespaces now.</p>
<p>The trailing whitespaces might not do any harm for the currently accepted version, but we’ll have to warn about them if we decide to add the trailing backspace. As currently accepted we still have a hole to fill for coding styles, we do not support multi-lined string literals for code formatting only, nor do we have trailing precision for the same matter. (That’s what the backslash was meant for.) That said, I cannot break up a really long hardcoded string, which in my IDE is softly wrapped, into a multi-line string literal so that it looks in every editor the same and still expect the same result and be precise about the trailing whitespace characters.</p>

<div class="">Cosigned. We already have an Xcode setting to strip
trailing whitespace, a Git setting to flag it, and linter settings
to remove it. (For instance, SwiftFormat has a --trimwhitespace
flag.) Not every tool needs to handle every case of questionable
style.</div>
