There are proper algorithms for binary diffs https://www.daemonology.net/bsdiff/ And yes, all binary patches (especially with line-oriented algorithms like what diff uses [1]) are incredibly brittle and I could expect specific binary diff programs could use a lot of checks to make sure the patch is properly applied. diff/patch has obviously absolutely nothing in that arena.
