If we don't count the WAL files, though, that eliminates the best way to detecting when archiving is failing.
WAL files don't give you this directly. You may think it's an issue to get a lot of WAL files, but it can just be a spike of changes. Counting .ready files makes more sense when you're trying to see if wal archiving is failing. And now, using pg_stat_archiver is the way to go (thanks Gabriele :) ).
