Still missing scenario:

Document allows custom dict key-value pairs and updates them to tags

d = Document({'id': '123', 'hello': 'world', 'tags': {'good': 'bye'}})

assert d.id == '123'  # true
assert d.tags['hello'] == 'world'  # true
assert d.tags['good'] == 'bye'  # true

Pydantic model skips these key-value pairs, which means if the client's (frontend) json payload has additional key-value pairs, they wouldn't get passed to Document()

PROTO_TO_PYDANTIC_MODELS.DocumentProto(hello='world')
# DocumentProto(id='', content_hash='', granularity=0, adjacency=0, level_name='', parent_id='', chunks=[], weight=0.0, length=0, matches=[], mime_type='', uri='', tags={}, location=[], offset=0, embedding=None, score=None, modality='', evaluations=[])

This is done.
