OpenMetrics 2.0 does not include the protobuf representation. For available formats see [this](https://prometheus.io/docs/instrumenting/exposition_formats). |

WG discussion:
- Mention only that it does not include OM proto anymore.
- Deprecation might mean we should update 1.0. We just don't continue OM proto in 1.0. Actually deprecation should be in 1.0 (outside of the scope).
- David: We don't need to say other protocols.
- Idea: Mention negotiation and alternatives being possible and the intention of exposers to support both OM text and protobuf. Although it does not look this belongs. Maybe without normative language

Consensus: Just context and link to exposition format, mention the desired (if acceptable) dual expose format imple etc
