Bad sd_vector_builder order

[AkumalexTheExalted]

Hi,

I use sd_vector_builder to create my sd_vector.

Without realizing it I didn't fill out the sd_vector_builder in the right order (with set) and it didn't crash.
I could still create a sd_vector, but it was an erroneous one.

Is it normal that the sd_vector_builder does not crash ?
If yes, is it possible to clearly indicate in the documentation that the code will not crash but that the result will not be correct?

Thank you,
