The `expand` callback is 'trivial' to replace, since it is only iterating over ID pointers and calling a callback. The only change in behavior here is that some pointers that were not processed previously will now be. In practice this is not expected to have any real effect (usually the IDs used by these pointers would have been expanded through other usages anyway). But it may solve a few corner cases, undocumented issues though. Part of implementing #105134: Removal of readfile's lib_link & expand code.
