Granular control of access to a specific fields/group of fields by users/groups (i.e. not all or nothing to edit metadata)

[#1]

Request for Feature Enhancement (RFE) Summary:	No granular control of access to a specific fields/group of fields by users/groups (i.e. not all or nothing to edit metadata)
Use-case:	Currently, we cannot prevent users from updating a certain field only or groups of fields in the properties. It’s either the user gets to edit all or none. This impacts creative rating and commenting. Ideally, we would want to allow asset consumers to be able to post comments or reviews, rate assets but not edit any metadata. Due to this existing restriction, only our group librarians can do that.
Current/Experienced Behavior:	No flexibility to set-up granular permissions
Improved/Expected Behavior:	Be able to set-up granular permissions
Environment Details (AEM version/service pack, any other specifics if applicable):	ACS
Customer-name/Organization name:

Hi @mikeetiuPH 

Can you clarify how this can not be achieved through ACLs ? I may not have understood your point correctly

[#3]

@hamidk92094312 - we can't. Coz it's always all or nothing. We cannot target a specific metadata field in the ACL

@akashk22786878 can you please look at this Idea and review it? Do we need more information for this one?
