@Robert: Firstly, could you define "suddenly gets _new support_"? And 
in that regard: these days, Opera, Safari and Chrome get support for 
extensions. Thus it should be possible to implement navigation toolbars 
based on these link relations even if the user agents are not shipped 
with such support built in. Hense, unless the mentioned browsers 
suddenly - or in due course - will remove their extension support, this 
does not seem like the right moment to anticipate less support.

@Anne: so if Opera suddenly removes it, we should change the spec ...? 
And what is "this feature"? Please note that the change propoposal does 
not speak about whether user agents should have specific toolbar 
designated for structural navigation of a web site based on link@rel 
keywords - or not. The CP merely seeks to speak for a conservative 
interpretation of certain @rel keywords. The reference to Opera's 
implementation in the Alexandre Alapetite's overview over the status, 
mereley show that the interpretations deviates very little from each
