As I see and discuss with @dzhdanov, add and offset are pretty much the same functions with different descriptions and small implementation details.
Describe the solution you'd like
One function should be an alias to another with only one implementation
Describe alternatives you've considered
The alternative would be to leave it as it is, but now it doesn't look good, even from the documentation side: add vs offset
