I believe this happened in 5.2, and it was a fix to a regression introduced in 5.1, when they switched the form generator from form_for (which already had automatic IDs generated by the tag helpers) to form_with, which removed those.

Rather than restoring the magical automatic ID attributes, the scaffold generator was updated to include the id: 'whatever_attribute' directive in the individual tags, and the tag helpers were left alone.

Previously, if you wanted to suppress the ID for a form element (say, if you needed to have two or more identical elements on the page -- think: a bunch of checkboxes for the same attribute), you would have to pass id: nil or id: false (one of those) to the helper. Now, that's the default behavior, and if you want an ID at all, you have to tell it what you want that ID to be. I'm not sure where the edge case is here; whether it's more common to want no ID, or to have a nice unique one generated for you for free. It's clear what the framework designers chose.
