In the FAQ it just says "Come on" for SQLite included in the list. Can you provide a bit more detail? This feels like a pretty great option to include here.

My theory: everybody knows sqlite can be distributed as a single-file library that you can happily embed. However, it's a pretty complex beast compared to the rest of the list and maybe it's outside the vision of the list altogether, which features much simpler projects.

Edit: to be even clearer, sqlite is 100+ .c files. Yes, you can make it one "amalgamated" .c file, but no developer works on that file; they work on the 100+ smaller .c files.

I guess you mean SQLite developers don't use the amalgamation. It is used by users.

The amalgamation is used for instance in the most popular Golang library to provide SQLite engine.
