Possibly relevant to https://github.com/modelcontextprotocol/python-sdk/issues/1664

> I think there's a version of the supported spec somewhere? That would be [here](https://github.com/modelcontextprotocol/python-sdk/blob/9dad26620f8ec75098d53acafa59b495d4342850/src/mcp/types.py#L32) - audio content was added in that version, `2025-03-26` (see [here](https://modelcontextprotocol.io/specification/2025-03-26/server/tools#audio-content), [here](https://modelcontextprotocol.io/specification/2025-03-26/client/sampling#audio-content))

Also noted in the release notes [here](https://modelcontextprotocol.io/specification/2025-03-26/changelog#other-schema-changes).

Is this behavior SDKs allow today? Would be interested in seeing at least one or two code references.
