It's so that we diagnose a member function marked with `exclude_from_explicit_instantiation` that is used but not defined just like we do for an `inline` function. This causes us to `push_back` the declaration (line 668 below) into the vector of `Undefined`-but-used declarations, which we use to trigger a diagnostic somewhere else.
