I was surprised to see SQLite listed as a source but not as a destination. Any big reasons for that or is it just something you haven't got around to implementing yet?

I've been getting a huge amount of useful work done over the past few years sucking data from other systems into SQLite files on my own computer - I even have my own small db-to-sqlite tool for this (built on top of SQLAlchemy) - https://github.com/simonw/db-to-sqlite
