Why would you write something like this? (intentionally not using delete [] on an array)

Question

I came across this kind of code once in a while - I suspect the creator is/was afraid that table delete would iterate over the table and "cost performance" (which imho will not be done either way)... is there any real benefit one might get/consider/imagine from not using the the table delete here?

myClass** table = new myClass* [size];
... //some code that does not reallocate or change the value of the table pointer ;)
delete table; // no [] intentionally
