I created a sub account for myself just so that I could restrict access to my credit card when for example friends or young kids use my PlayStation. It's incredibly stupid that sub accounts can't be upgraded. I know there are a lot of accounts to process, but this should be something that we can do. People who have grown up with sub accounts should be allowed to have a master account as people are saying, especially if important functionality is not possible with it.
