Modify security model of IGC Catalog permissions

Reference this support case:

We are currently attempting to implement a security model for Information Governance Catalog (IGC). The security model we would like to implement needs to take into account that our system supports multiple businesses. I plan to implement the model by using Catalog permissions, creating a top level category per business and allow appropriate access based on restricting access to certain groups.
We would like all users across all the businesses to be allowed read access to the entire repository so that all businesses can read all categories and terms for every business we support.
Additionally we would like author/s from each business to be allowed write access only to the categories that they own.
Plan is to create a group which has only IGC Basic User (effectively read-only) access, lets call it RO-Group.
Also plan another set of groups, each with Information Governance Catalog Glossary Author (effectively read-write) access (RW-Group-Business), one for each top level category.
Category permissions config to be as follows:
1) Every top level category allows access to RO-Group
2) Each top level category allows access to the group with Author access for that category e.g. Top Level Category A allows access to RW-Group-BusinessA, Top Level Category B allows access to RW-Group-BusinessB etc

My preliminary testing shows that if a user is in both RO-Group and RW-Group-BusinessA, and RO-Group is granted permission to access Top level Category B, then the user is able to edit details in Top level Category A as expected but also allowed to edit Top level Category B, which is not what we want.
It's as if access is granted to a category based on whether a user is part of a group that has any level of access, and level of access is determined by the maximum level of access a user has given the groups he is part of, irrespective of whether the higher level access group is allowed access to the category.

Support has advised that this is a current limitation of the IGC access model and suggested raising a RFE to support our requirement. So, in short RFE is to enhance IGC Catalog permissions such that level of access a user has to a category is determined by the maximum level of access of groups which are allowed access to the category.
