My first thought is that frequent and disparate traffic makes Tor more secure against certain attacks. Including Tor in Brave makes Tor better.

Also, I can imagine some instances where you want to obfuscate your IP location to the visited site/service, but don't much care if your DNS requests leak because you're more concerned about the accessed site/service generating a patchwork of locations associated with a specific user and less concerned about your ISP or DNS provider knowing generally that you connect to the site/service.
