There was a problem hiding this comment.
what do you think about putting something like
val isRequired: Boolean
get() = rawBytes.array.first().toInt() != 1
in the UnknownField.Value class and then having
options.unknownFields[it]?.values?.firstOrNull()?.isRequired == true
here?

Maybe not isRequired because it is just a boolean. We need to smart cast those bytes to a boolean, maybe something like asBoolean() is a better candidate.
