This is mistaken. The Go module proxy doesn't make any guarantee that it will permanently store the checksum for any given module. From the outside, we would expect that their policy is to only ever delete checksums for modules that haven't been fetched in a long time. But in general, you should not base your security model on the notion that these checksums are stored permanently.
