Thanks for trying this out, I've tried fiddling with various
width/height scale() and stroke-width values but I haven't been able
to produce anything that doesn't look like crap. Maybe someone else
can make something better?

It does, I just hadn't noticed, and it's pretty useless to only have
it at z17 for such a large feature, see for example:
http://server.tah.openstreetmap.org/Browse/slippy/?zoom=17&lat=64.80604&lon=-23.77402&layers=BF

I'm experimenting with adding rules to z12 to render the name at that level.
