Review Comment:
Yes , map serialization is none deterministic by default, and
`SetSerializationDeterministic` to true will make it deterministic.From the
document above `This means that for a given binary equal messages will always
be serialized to the same bytes`.
I've also tested and it's deterministic as expected
