I hate the way so much of programming is just fiddling knobs on some old systems. It always gets to a point where I would prefer to rewrite the whole thing myself with only the functionality I need and to truly understand what is going on under the hood. I just wish these projects were built in a modular way so you can re-assemble parts of them back together easily.

Google didnt, thus Chrome started replacing sqlite with https://github.com/google/leveldb
