I agree with most of your suggestions, but I wouldn't use "safe_load" unless the file has untrusted input (in which case, you could argue, you shouldn't be using YAML at all). If you use safe_load then you'll get an exception if you use dates or timestamps, even if it's an unquoted string that happens to look like a date (but you can get around that last one by quoting).
