Is that true? I thought deprecation warnings appeared directly when viewing a page that used the deprecated code - that was my recent experience of this with the WikiPage/Revision stuff that is deprecated in 1.35 - I was experimenting with an extension (in development mode) that hadn't fixed that issue, and the warnings appeared right there on every page.
