include_history for object store watch have no effect

[kfollesdal]

Observed behavior

Object store watch function have parameter include_history. If False delivery policy is set to LAST_PER_SUBJECT:

nats.py/nats/js/object_store.py

Line 498 in 7e7883e

if not include_history:

If set to True then deliver_policy = None and then default to ALL:

nats.py/nats/js/client.py

Line 420 in 7e7883e

# NOTE: deliver_policy is defaulting to ALL so check is different for this one.

But messages in underlying meta jetstream for object store is published with Nats-Rollup: sub. So we only have one message for each subject. So with this LAST_PER_SUBJECT and ALL will give same result at consumer start up. If I understand it correct?

Expected behavior

Expect include_history= False to give delivery policy NEW, only receive new changes from start up.
