So this is enabled by default. If user do not want source gen version, they have to explicitly set this prop to false in their csproj?

[satvu]

Yes - the current behavior is that the generation of the file happens automatically so I followed that and added this prop to disable it. Pros and cons for either default - mostly depends on how we want this rolled out and how we want customers to opt-in (more steps, less steps?).
