I don't know, but Brendan Eich (Brave's CEO) [1] is pretty active on Twitter, and I think he used to answer the questions people asked. You could try asking him there. Let us know if you get an answer.

Also, I apologize for being a little bit too harsh in my previous comment.

Do you mean that they don't offer an option to route all your web traffic via their servers?

Do you think that this is something browser vendors should do, ie. that the absence of the feature is something that must be explained?
