This feature should be indicated as experimental.

Also I'm not sure about the phrasing "content blocking mechanism" sounds rather
vague, as the old mechanism could arguably also described as such.  I don't have
an ultimate opinion, but here are some examples that sound more accurrate to me:

"Use Safari's native content blocking mechanism (experimental)" 
"Use Safari Content Blockers (experimental)"
"Use native Content Blockers (experimental)"

Make sense. What about "Use Safari's native Content Blocking (experimental)"?
Because I noticed that they consistently call it "Content Blocking" on
https://developer.apple.com/library/ios/releasenotes/General/WhatsNewInSafari...

[Sebastian Noack, 2016/02/26 15:20:14]

Except when they call it Content Blockers:

But I guess either should be fine.

[Thomas Greiner, 2016/02/29 17:32:42]

Done. Maybe they're referring to the product as Content Blocker and to the
feature/mechanism as Content Blocking.
