While I agree with most of what you're saying, I don't think we 
should prioritize performance over accuracy or correctness. 
Especially for numerics people, precision is very important, and 
it can make a just as bad first impression if we don't get this 
right. We can however make the note in the documentation (which 
already talks about performance) a bit more prominent:
