Sure but, the question is: Is acceptable for wine to crash when dxtn library is missing?
In some cases, yes. That is, it isn't necessarily Wine that's crashing here, but the application itself. Wine will refuse to create DXT/S3TC textures if those are not supported by the driver, but applications won't necessarily respond well to that, since in practice DXT/S3TC textures are always supported on Windows. There isn't a lot we can do to make that better.
Fedora does not ship this library by default for patent reasons.
Not even the "s2tc" implementation? As far as I'm aware that one doesn't have known patent issues.
