That would allow for an array of ["str1", "str2", null, "", "str3"], with null indicating a read failure.

SBStructuredData::GetStringValue returns a `size_t` which is the complete size of the string, so it can be called with nullptr or length 0 to find the complete string size, then re-call to fetch.  Or we could add a GetValueString() API that takes an SBStream like other
