I'd like to share for discussion a draft BIP to allow for a modular mempool/relay policy: https://github.com/bitcoin/bips/pull/1985
Javascript implementations are notoriously bad at safe sandboxing. The most well-maintained, V8, has security vulnerabilities fixed nearly every month.
Additionally, using the filesystem as such is a "power user" task, while many people running nodes are (or should be) ordinary end users who don't necessarily understand these concepts.
I think a better path forward would be some kind of simple domain-specific language. This way it could be designed to make abuse (eg, for censorship) difficult, have an end-user friendly interface, and allow for transparent native optimisations (or even profile at runtime to reorder classifiers as optimal for the fastest reject).
However, I do understand this increases the complexity significantly, and so your concept may be "good enough" in practice, at least as an initial proof-of-concept. But I would finish and test that POC in the real world first, before exploring a BIP for the interface.
