Creating data groups for easier managing ACL's

From working just a little with ACL's but a lot with the customized datafields in relations to contacts and events it is my point of view that following changes can ease setting up data access limitations:

Either:
1) Making two groups for customized data-fields: "Standard" and "Special", and then changing the ACL rule of "access all customized data" to "access all standard customized data", so that this grands access to all in "standard" group. Data-sets in "Special" group needs to assigned through CiviACL manager.
2) Same as above but with only the "Standard" group defined, and other groups must be created by the user: for example "HR" and "Teacher" so that fields ever added to the "HR" group can be accessed by everyone who is allowed by that one ACL rule, and so fourth with the "teacher" group.

I think this will ease the use of ACL's a lot!
