A common pattern is to set an IDL string field using an explicit StringData, such as idlObject.setStringField(StringData(something.toString())). This isn't usually needed, though it doesn't cause any major problems right now. However, with SERVER-90167, we'll support setting IDL string fields by move, so passing a StringData instead of an rvalue string will inhibit a move.
I've identified 28 places in non-test code that are likely instances of this pattern. These may not all be instances of the pattern, and most of them won't inhibit a move - some definitely will though (e.g., 1 2 3). Still, we should probably get rid of the StringData conversions here, at least where the thing being converted is a std::string.
