Almost nobody cares about anything other than ad blocking and to top it off the reply to the comment you linked is even mentioning that they were only talking about ad block...
You may be right, but I have no trust in Brave. Not just due to their shady decisions in the past but also because they would have to fight a huge ad industry on a tiny budget with their built-in ad blocker. At least if it's an add-on, the community would be able to help easier.
