Turns out that the wiki page I mentioned isn't exactly how it's currently done 
in Belgium...

On the NGI maps I have the rules they use to classify roads are almost the 
same as OSM, but they're using them much more strictly than us (I'm not 
talking about motorways or trunk roads here):

NGI rules:

N#, N##, R#, R##: primary
N###: secondary
Road numbers with letter suffixes use same classification as if the number 
didn't have the suffix.
other important roads: tertiary

OSM Belgium guidelines:

N#, N##: primary
N###: secondary
Road numbers with suffix: primary or secondary whatever makes most sense
R#, R##: primary or secondary, whatever makes most sense given the other roads 
that cross the R-road
primary roads within an R-road become secondary
primary/secondary changes possible if they make sense
other important roads: tertiary
N- and R-roads can be downgraded to unclassified or residential if they're 
really just a local road.

So, drop all the "making sense" bits in the OSM rules, and we get the NGI 
rules :-)

But the wiki page should be adjusted to get the above rules, as that's how 
almost all of Belgium is currently mapped...
