           Avoid usages of whitelist & blacklist, in favor of more inclusive and descriptive language.
           For consistency, favor 'allowlist' and 'blocklist' where possible, but other terms (such as
           denylist, ignorelist, warnlist, safelist, etc) may be appropriate, depending on the use case.
