Exhibit A: https://gerrit.wikimedia.org/r/168419 Caused, I think, by deprecation of the { ok: ..., err: ... } way of setting callbacks in mw.Api, but not totally sure. If that *is* the reason, then we never saw any warnings about it to my knowledge... It may just be that we missed it, but if not, I figured it should be raised that a warning would be nice.
