It doesn't require nearly as much storage as you think. For zig, there's only 3 standard libraries (glibc, musl, mingw) and 7 unique architectures (ARM, x86, MIPS, PowerPC, SPARC, RISC-V, WASM). LLVM can support all of these with a pretty small footprint and since the standard libraries can be recompiled by Zig, it really only needs to ship source code - no binaries necessary.
