[Request] Flag to handle google wrapper types

[ff-ils]

It would possible to add a switch to handle in a different way google wrapper types, to map them to base types, like when using optional keyword? It would be not compliant, but the use case is this: in c#, if a field is "optional int32" it becomes an "int" instead of "int?", while in TypeScript it is (correctly) "number | undefined". The only way to have an "int?" on the c# side is to use google.protobuf.Int32Value, but on TypeScript side it is no more a base type.

So now you have to choose between

| c# | TypeScript | | int | number? | | int? | google.protobuf.Int32Value |

The request is to add a switch to handle wrapper types as if defined as "optional" with a base type, to have "int?" <--> "number?".

So the question is to generate google.protobuf.Int32Value field = 1 as field?: number?

Yes, we want to do that. I'm closing this as a duplicate of https://github.com/timostamm/protobuf-ts/issues/181, but thanks for bringing it up.

Unfortunately, we can't implement this yet. We need to switch our code generator to use @bufbuild/protoplugin under the hood first, so that we have more flexibility in the plugin. There hasn't been much activity on that work lately, but it's still the best way forward.
