I see there is record o _createdAt and _updatedAt, what if I want to include the track of _createdBy and _updatedBy. it should be opt-in to enable this by default. one way is to create attribute for that, but it should by default can do. (giving it Null or annoymouse if no auth required to make change)
TL;DR
Developers want to track document changes by including _createdBy and _updatedBy along with _createdAt and _updatedAt. They want this feature to be opt-in and enabled by default. One solution could be creating an attribute for this purpose, with the option to give it null or anonymous values if no authentication is required.
