> Deprecation of these commands does not mandate that they are removed at the first opportunity. It only indicates that we want to move away from them.
> Rewriting these commands so that they call the pkey replacements looks to be very difficult. Reproducing the exact behaviours will be challenging, although the basic functionality would be straightforward.
> The rsautl command is deprecated and isn’t slated for being restored — pkeyutl is every bit as easy to use.
> The -dsaparam option to dhparam is deprecated — it cannot be supported without direct access to low level functionality we want to remove.
> Post quantum crypto will make the discussion obsolete — none of these algorithms are useful in a quantum computer world.
> My personal opinion is that these commands are good being deprecated but that we should not remove them until their usefulness is at an end. This will likely mean not removing them after five years of deprecation. It would mean removing them once quantum computers are shown to be effective. Without deprecation now, we can’t remove them until a lot later.
