Cluster level managers require bucket connection?

with Enterprise Edition 7.0.0 build 4554 with couchbase latest: 3.1.1

1) this code:

async function go() {

  const cluster = new couchbase.Cluster("couchbase://localhost", {

    username: "Administrator",

    password: "password",

  });

  // const bucket = cluster.bucket("travel-sample");

  const bucketMgr = cluster.buckets();

  await bucketMgr.createBucket({

    name: "hello",

    flushEnabled: false,

    replicaIndex: false,

    ramQuotaMB: 100,

    numReplicas: 0,

    bucketType: couchbase.BucketType.Couchbase,

  });

  await bucketMgr.dropBucket("hello");}

raises "Error: You must have one open bucket before you can perform queries."

However it's documented that this only applies for versions older than 6.5?

2) uncommenting the `const bucket` declaration makes the code work, if the bucket exists.

3) uncommenting the `const bucket` declaration with a bucket that does not exist, ends with a "Error: cluster object was closed" error.

(obviously this is User Error... But it's confusing as the bucket connection shouldn't be needed, isn't used, and the error message is misleading.)

I believe this is the confusion behind https://issues.couchbase.com/browse/DOC-7990

So far seems to be just affecing Node SDK? I couldn't replicate in cbshell, and David Kelly has tested "works fine without opening a bucket first, on 7.0.0 build 4797, and a 6.6.1
That’s with the current master on LCB
Same thing with the current python sdk and current bundled lcb (3.0.6)"
