with this header proposal there isn't any limitation to this on every 
request ...

after the 3rd question you will allow it for the whole site, believe me ...
otherways the non existence of a serious use case is just proven ...

in comparison to the header proposal, the JS Geolocation API is used 
only when needed, because, you have these JS at every page then ...

in times of big bigger biggest data, you won't believe this yourself 
..., that this will happen;

just think of this HTML

<IMG SRC="">

with the header proposal, there will be sent the location data, with the 
JS Geolocation API, it would be quite strange ...
of course, you would be asked to allow this, but in case you have 
allowed earlier for the

and now think of bad boys who put this HTML Tag anywhere; then you 
wouldn't take a notice
that you have sent your location to, even your browser shows
because you have allowed this, earlier ...

now you see with my explanation, that there is raising the vector in a 
not acceptable way ...
and the optimization you are talking about doesn't really make any 
sense, when you are talking serious about the
problems you're raising ...
