SafeMemoryWriter doesn't have a lot of @Override annotations.

We tend not to use them (rightly or wrongly is a different question, I'm just 
sticking to the standard practice)

Fyi, the code style practice is that we do use them but not when implementing 
an abstract or interface method. I'm sure there is many places that misses them 
when they should have it but those are oversights and we shouldn't follow those 
bad example if possible.
