I think this could be a bit less specific to support additional/different args to both env and v. Maybe something like "^#!\\S*env( .*)? v " ?

Yes, you are right. Maybe we can agree on ^#!\\S*\\benv(\\s.*)?\\sv\\b?

That seems reasonable. The v\\b has some potential to cause false positives but they would probably be rare enough. I don't know of any popular tool or language that would use eg. v-something or v=something.
