Nice work! I have a similar "better" redis-cli that I unfortunately never cleaned up enough to release but the two features that I built this tool for you have also added: 1) the ability to connect via TLS to a Redis instance and 2) the ability to add aliases (or DSN in your case) for easy accessibility.
On the topic of TLS connections, taking a super quick glance at the source code [1] and the documentation it looks like you've added support for this but I couldn't get it to work. I think it's failing silently and defaulting to 127.0.0.1. I tried using `--url` and dsn_alias in an `iredisrc` file. Unfortunately you don't have a flag to toggle TLS so you can't connect using TLS using only individual flags (`-a`, `-h`, etc.)
