Thats not the case, the snow spec contains no limit in the place where
we need to check. Its a natural and expected limit so likely all files
will be within that but a file outside would still be arguably valid.
So a valid file could potentially be outside this range and the
maintainer (that being me) need to know about this.
Please dont see every change that originated from a fuzzer generated
report as only related to fuzzed files.
