Similar functionality is provided in nftables for linux ('inet' filter applies to both ipv4 and ipv6). But, outside of the most trivial use cases of just block/allow a port, it doesn't really work out to be that useful because of other restrictions. E.g., if you are collecting IPs that have e.g., created new connections to some set of ports greater than n times within a time period to rate limit them, you are out of luck and will need separate rules for ipv4 and ipv6 since you cannot save a mix of ipv4 and ipv6 addresses to the same list.
