Part of the reason is that ensuring things work for a different CPU architecture is simply a non-trivial task. There are libraries with hand-written x86 assembly, and others in C/C++ that depend on x86 intrinsics to perform acceptably, and then there are those that work accidentally on x86 because of how compilers implement some undefined behaviour for x86.
