To answer that, I need to know why you think VLAs are considered bad
practice.

VLAs on the stack are a bad practice because (1) they may use too much
of the stack in an unexpected way, and (2) they require extra registers
that ruin optimization in the whole function.

Obviously, it does not apply to pointers to VLA.
