My friend and I had a similar idea a few years ago, so we’ve built a prototype of a tool that converts personal data exports to a single SQLite database: https://github.com/bionic/bionic (repo includes “popular Spotify songs when I’m in transit according to Google Maps” query). Unfortunately, we haven’t found ourselves actually using the aggregated data: we’ve looked on it a few times, but it didn’t end up solving some real pain. It was fun to build though!

I've had a few uses for PDPL so far and I'm trying to add functionality when I need it rather than taking a shortcut and just writing the script I need in $LANGUAGE. But, like you said, it was fun to build and I learned a lot so if it's not useful to me or anyone else, that's OK too!
