First, it's good to distinguish raw data from C strings at the type system level, and second, the unpredictable signedness of char is actively bad for byte-oriented processing. Another library making a different choice doesn't overcome these reasons.

I don't know where you get this idea from -- SerializedScriptValue has always used uint8 buffers. That IndexedDB used Strings and that _it_ changed to uint8 buffers is entirely irrelevant here.
