Surprisingly extensive article from Brave[1] from Aug 2018 -- two years ago! About redirect tracking, it says this:
> Brave’s policy of disallowing any third party state by default makes it already more privacy-preserving than ITP 2.0 in regards to third party redirection-based tracking. Brave users however may benefit from an ITP-like protection from first-party trackers, although their number is small.
Apparently Safari had ITP, a similar type of redirect tracking mitigation, for some time.
