It makes a lot more sense to ask a synthetic child provider to change a value - since it does represent the value of the ValueObject - rather than the summary which is just some free-form text. And being able to change characters in a string seems a reasonable thing to do, so switching the std::string comprehension from a Summary provider to a Synthetic Child Provider is the way to do that. So that part if fine.

So, is it Ok to use current `SetValueFromCString` api from ValueObject to ask synthetic provider to update the underlying string?
You mentioned previously that we may add `SetSummaryFromCString` api - in fact currently this is what I am doing - changing the whole string through its summary (please check attached gif for example).
But the problem with the new API is the same as for the changing characters through `SBValue::GetData` - IDE doesn't support it
