Not the whole OSSL_PARAM array, just the data pointed to by (some) of the elements of one.
_alloc_ instead of _construct_ makes sense and is better than NULL.

I’m fine with `OSSL_PARAM params[20]` in code and filling as many slots as desired.

To do entirely heap allocated arrays, we’d want to go via a stack (which is something we shouldn’t require providers to depend on) or use a linked list of some kind.
