This wouldn't be the first time we NIH'ed something, so that by itself
isn't a sufficiently good reason to not use it :)

Well, you skim over performance, it'd be nice to get some figures of how
much faster/slower it is. Binary size may also be a factor in some
situations (if zlib is included static).
How often is zlib not available? I mean, afaik, it's even present on MSVC
builds or iPhone/Android builds. I think we sort of have to quantify how
much of an issue this really is.
