Absolutely agree that a general purpose replacement for Xlib would be a massive pain, but providing sufficient support for the core protocol to let you add whichever request types you need is quite simple (and I lifted that from a decade old starting point and made it work).

And for my use I only need to support about a dozen requests types, and no third party libs, so it's not that bad. My starting point only linked with Xlib anyway, nothing else, and I verified which requests Xlib actually sent via xtruss before I started.

But of course, that's because I only want to actually use it for something very simple. If I wanted to do something more complex I'd wrap a higher level library instead.
