+BMIs are not and should not be treated as an information hiding mechanism.
+They should always be assumed to contain all the information that was used to

Done by adding the suggested text to the above section about ``-fmodules-embed-all-files``. I feel it is odd to mention ``-fmodules-embed-all-files`` in the current section since it is mostly about clarifying that hiding information is not a goal for BMIs. It is true with and without ``-fmodules-embed-all-files``.
