Nice! I don't think you even necessarily need OP3 to get some sort of analytics. You can self host and get some analytics based on requests or if you're using a provider like Spotify Creators (formerly Anchor), and it gets a little more precise with some data like # of subscribers and demographics since Spotify has sufficiently high market share, and there's some services out there where they solely focus on estimating podcast analytics.

Where just about everyone lands on it is hosting is better off and more cost-effective outsourced to the specialists so that burden can be taken off the podcaster. But of course, there's something to be said about fulfilling curiosity. 😉
