Good security policies should have an upper bound on password length, but also those upper bounds should maybe be like 100 characters or so. There's a couple reasons for this. First being is that hashing does take some compute resources, second being that there is some security/usability tradeoffs here, etc, and third being that after like 30 characters or so, the effective (key phrase here) security gains become marginal.
