Can I specify a dict key with arbitrary JSON-legal characters in a FieldCondition?

I originally posted this as a feature request (#5146), but it hasn't received any comments, so I'm posting it here as a question (apologies if I'm breaking any rules in the process!):

I am storing unique tags in my payload as the keys of a dict (metadata.tags), rather than a list, because that enables me to append a new tag idempotently to multiple points at once:

  client.set_payload(payload = { tag: True }, key = "metadata.tags", points = points)

which is very clean and efficient. And I can query them with:

filter = QdrantFilter(
           must = [
               FieldCondition(
                   key = f"metadata.tags.{tag}",
                   match = MatchValue(value = True)
               )
           ]
       )

which also works great. However, a problem arises when my tags include legal (JSON) characters such as "/", because the "foo.bar.baz" key syntax breaks when you include certain characters in a naked key like that. For instance:

 key = "metadata.tags.tag-with/slash"

generates a parsing error, even though "tag-with/slash" is a JSON dict key.

I would like to be able specify my key in such a way that non-compatible (but JSON-legal) characters can be escaped. For instance:

    key = f'metadata.tags["{tag}"]'

which would echo jq's alternate query syntax. But I'd be happy with any solution.

Nevermind: false alarm: it turns out that it does already work if you use the syntax key='foo.bar."complex/string"'. Don't know why I thought that didn't work when I first tried it!
