I think we should also add all fields should be marked optional? Unless that's in a different AEP already.

@toumorokoshi Do you mean when using proto3 syntax all fields should be marked optional? When using 2023 and above, it's all optional by default, so no optional directives needed.

[odsod]

I can add another paragraph under the first one saying:

When using `proto3` syntax, fields **should** always be marked optional.

But I think it's a bit orthogonal to the syntax directive, so maybe better specified somewhere else?

@toumorokoshi How about this?

[toumorokoshi]

That sounds great! Yes, I was referring specifically to proto3. 2025年11月12日(水) 4:38 Oscar Söderlund ***@***.***>:
