/laukika Sanskrit is the sort of Sanskrit we should speak, as opposed to the old Sanskrit heard in the veda.
/laukika Sanskrit follows pANini's rules; those rules, in turn, were based on some variety of language that was commonly spoken in /pANini's age. And that is why the grammar has a rule teaching us the proper way to address a female jackal. /pANini was unable to just make up grammar rules, he had to make rules that gave as a result what people of his time were already saying.
