Describe the solution you'd like
Ability to "PATCH" a User record by sending something like username and maybe org. name to a new /user endpoint and additionally sending activate/deactivate switch as 1 or 0.
The API should respond with the number of records successfully updated (ex: 1 user record updated successfully, or a return an error (ex: error updating user <username>. <error message with details>).

For visibility - this isn't currently on the roadmap. I'll convert this to a discussion so we can poll the broader community and gauge interest.
