Description:
No storage engine ever sets HA_REQUIRES_KEY_COLUMNS_FOR_DELETE, and this includes 3rd party engines I was able to check. Removing this would allow cleaning up some dead code where this flag is checked.

How to repeat:
Read source code

Suggested fix:
Remove it

Hello Laurynas,

Thank you for the report and feedback!

regards,
Umesh
