* In `maybe_create_table()` and `maybe_add_column()`, the response of `$wpdb->query()` is set to a variable that is never used.
* In `make_db_current_silent()`, which is a wrapper for `dbDelta`, a variable is set that is not used. This function appears to be a copy-paste of `make_db_current()`'s `dbDelta()` call but is meant to return nothing, and still does not.
