Limiting owner key's role to only changing keys

What happens to the people who have the same key set for everything? A quick hivesql query(SELECT * FROM Accounts WHERE owner=posting AND owner=active;) shows that there are 18080 accounts like that. A lot of them were threespeak related, and changing the query to skip those(SELECT * FROM Accounts WHERE owner=posting AND owner=active AND owner NOT LIKE '%threespeak%';) still results in 15606 accounts like that. Will they be forced to change their keys? I'm sure that some people are actively doing that to use the same key. Checking accounts created in the last year(SELECT * FROM Accounts WHERE owner=posting AND owner=active AND owner NOT LIKE '%threespeak%' AND created > '2020-04-01';) results in 24 accounts. While thats not a lot(less than 2 per month on average), leaving the option for advanced users(I saw that marky and deathwing made a few of the accounts that have the same keys) to have more control over their keys would be best would it not?
