Here's a suggestion that may be of use to you that's based on the classic test helper class such as the one below which contains a few snippets of one I used recently for an org I was working in. I'll explain some suggested modifications at the end.

You'll notice I've included a number of custom settings in the above. The custom settings that I'd want to be private would be:
PrimAdmin_CustSttng__c Admin {set;}
PrimAdmin_CustSttng__c Admin1 {set;}
TBA_CustSttng__c TBA {set;}
All of the above contain information about UserID's, email addresses, etc that you don't want to be visible to anyone else.
The custom settings to be set as public would be:
global EHcc_CustSttng__c CC1 {set;}
global Pub_Boolean_A__c BoolA {get;}
global Pub_Bool_B__c BoolB {get;}
The first one simply is used to set whether or not a CC is sent with an error handler message. The latter two are booleans that I've added for the purpose of answering this post. By using a strategy of setting Booleans in a Public Custom Setting, values could presumably be changed if the Boolean were set to True. So by altering the above code as below, I believe something like this could potentially work as a solution:
global static PrimAdmin_CustSttng__c generateTestPrimAdmin(){
PrimAdmin_CustSttng__c Admin = new PrimAdmin_CustSttng__c();
if (Pub_Boolean_A__c.getValues('BoolA') != null && BoolA.Value == 'true'){
Admin.ContactName__c = BoolA.ContactName__c ;
Admin.UserID__c = BoolA.UserID__c
Admin.UserName__c = BoolA.UserName__c;
Admin.Email__c = BoolA.Email__c; // [email protected]
Admin.Name = BoolA.Name;
upsert Admin;
}
else if (Pub_Boolean_A__c.getValues('BoolA') == null || BoolA.Value == 'false'){
Admin.ContactName__c = 'Carey XXXX' ;
Admin.UserID__c = 'xxxxxxxxxx'; //(sandbox, prod)
Admin.UserName__c = '[email protected]';
Admin.Email__c = '[email protected]'; // [email protected]
Admin.Name = 'Admin';
upsert Admin;
}
else if (PrimAdmin_CustSttng__c.getValues('Admin') != null ){
Admin = PrimAdmin_CustSttng__c.getValues('Admin');
}
return Admin;
}
It would seem to me that using this type of approach would allow a developer of managed packages to have their private custom settings, yet also all them to "edit" them using public custom settings during development.
Note: I have not tested this, instead only taking the time to collect some snippets of code and modify them "on the fly" to present the concept for consideration. I do not develop "officially" managed packages as yet but can see where this approach would seem likely to prove fruitful. Obviously the runAs user in the code I presented would not be necessary. I included it to illustrate the source and context of the original code.
Protectedsettings just behave asPublicones when part of a Beta install?
