Even with the Legacy option on it doesn't seem to restore it, the only way I could find to get it back and its not exactly the same, was to add a custom group to Data tab (we just named it "from other sources" and add the second available From other sources option (From other sources [Get Data From Other Sources]) to the custom group like below.
Trying with what looks like the original From other sources (the one above the highlighted under the choose commands from column if All commands is selected) it doesn't seem to work either, we tried that as well.
Unless it is hidden somewhere else that we are not seeing when enabling legacy, and it doesn't seem like it from the screenshot some else showed, we don't see that option, but we do see Legacy Wizard show up when legacy is enabled just no From Microsoft Query Option like the above screenshot shows. My users already gone for the week, or I'd jump in and grab a couple more screenshots, I can supply next week if needed.
