So, as a long-time mercurial users, revsets in jujutsu were a major feature for me. And if you don't want to use them, don't. But if you are looking to treat your VCS DAG as a queryable database they are awesome. And, they are great for avoiding having to chain a bunch of commands together, inefficiently, to get the same effect. Although you still can do that if you really want to. Just like you don't have to use jq to query JSON - you can do terrible cursed things with grep and awk and sed and it'll even work for simple cases. But you might want to give jq a spin - and really there are strong parallels in how they work.
