I understand that you are striving for a balance between utility and nativeness but in this case, I think that this feature adds a ton of utility (for me, at least) to Orion without compromising on nativeness. Safari (and Firefox) users won't be confused as they can continue to use Orion just like they used their old browser and people coming from Chrome can also use their browser just like they used to – nobody gets confused and everyone can be happy.
Also, as @eirk pointed out, it's just Safari that doesn't have this feature so I don't see how this compromises nativeness either. If "Safari doesn't have this feature so we can't add it to Orion" is the argument here, then I don't see the point of Orion.
And since this has already been added (and later removed), this should be an easy fix.
I really hope that this gets added to Orion again.
