Some questions to help me understand this a little bit more:    - I assume because of the TFM updates requirement on dotnet/runtime, TFM updates can only happen in a dependency update PR. AKA it's part of the process of ingesting an update that goes from 6.x.x to 7.x.x.    - What does the `Major Version` impact? Is that just what gets set in local dev builds as the package version? So `7.0.0-dev` or `6.0.0-dev`.
