OOTB "Lock Payload Process" locks Pages and Assets, but Assets only recognise checkin/checkout

The OOTB "Lock Payload Process" and "Unlock Payload Process" workflow steps locks/unlocks pages and assets, but Assets do not recognise Lock/Unlock. This allows assets and Content Fragments to be edited while locked. Assets have a Checkout/Checkin functionality instead. 

Would you find out for us if Adobe plans to fix this in the near future?

In the meantime, we are creating a custom workflow step for "Checkout/Checkin Assets".

Thanks.
