Did you consider adding note='this is oneway=no because the default for 
motorway_link is oneway=yes'? :-)

Luckily, the motorway_links haven't been subject to an edit war in 
Finland. There has been some edit war and debate regarding cycleways 
(which IMO should be tagged as highway=path, segregated=yes/no, 
bicycle=designated, foot=designated, moped=yes/no, surface=*, 
lit=yes/no; others want it highway=cycleway, although the ways are 
almost never marked with a bicycle traffic sign only).

As you can see from the above example, I prefer explicit tagging too. It 
can be a bit overwhelming for beginners, but implied things and country 
defaults are nasty for anything that tries to interpret the map data.


PS: Any objections if the default style adds surface=paved to motorways 
and motorway links? What does the Vienna convention say about motorways?  
Does it require a paved surface?
