Redis [QUESTION] If the redis official willing to implement two new commands （CAS and CAD） to make easy to implments a distributed lock？

CAS：compare and set [cas key oldval newval] CAD：compare and delete [cad key expectedval]

At present, redis is often used as the implementation carrier of distributed locks in distributed business systems. At present, the implementation basically depends on Lua scripts. Is it possible to implement these two commands natively?

This is just a simple personal consultation， No offense.
