Would it make sense to disregard DSA entirely? I.e. mark it not_approved = true? Note, DSA is currently being defined as sunset with the current draft of FIPS 186-5. As this is still a draft, we cannot rely on it nor can we know for certain that DSA will be sunset.

In any case, if DSA is intended to be left approved, shouldn't there be a check: (a) that the key is >= 2048 and (b) the hash is SHA-2 (and SHA-1 for legacy purpose)?
