The rule idea is very neat, but not a core module and unfortunately cannot be used in the actual situation

Why not? It's pure perl so you can always just copy 'n' paste if you have to.

Also this solution implements a subset of the rules managed by the code in the OP that already works, but it doesn't add anything, specifically it doesn't address the problem of avoiding protected directories, so unfortunately the particular example fails to justify using Find::File::Rule as an alternative.

Did you try it? It does exactly what the code in the OP does, in addition to not producing any error messages. F::F::R is bright enough to not chdir into places it's not allowed.
