Right, it would at least work. If the plaza is a multipolygon, I think 
that we should only add a way for the outer line, not to inner lines, 
because the inner lines would obviously become routing islands, and any 
POI close to the inner ways could become unreachable by Garmin routing.

We might even add mkgmap:country rules to improve it further. In 
Finland, highway=pedestrian should carry the following defaults ("add" 
does nothing if the key is already present):
{add bicycle=yes; add maxspeed=20;}
In Germany, highway=pedestrian should default to {add bicycle=no} AFAIU.

Of course, highway=pedestrian is just one case of a routing island.  
Another case could be amenity=parking, as we saw from one message 
(regarding warnings for dead-end oneway highway=service) last week.  
But, I think that that one simply is broken map data (missing 
service=parking_aisle, and missing connections from them to footways).
