That's equivalent to static linking, but with extra runtime overhead. You can already efficiently ship updates to binaries with something like bsdiff or cougret

That's equivalent to static linking, but with extra runtime overhead. You can already efficiently ship updates to binaries with something like bsdiff or cougrette, so the only reason to bundle shared libraries in an archive is for LGPL license compliance, or for poorly thought out code that wants to dlopen() itself.
