Except for this pesky line in the wiki page, which is what implies the 
presence of all housenumbers on an interpolation way:

"For missing house numbers (e.g. missing "12") two ways need to be drawn 
(e.g. "1-11" and "13-25")."

This is impractical anywhere I've been. It requires not only the creation 
of a new interpolation way each time a housenumber is skipped, but actually 
requires surveying each house to know what numbers are skipped. I can get 
each housenumber when surveying when they are nice enough to cluster 
mailboxes together, but it's time consuming (too much so in low light 
conditions), and I still miss some for privacy/safety reasons (people or 
traffic present). More often than not, I just get the houses at the end of 
each block. If the street signs are nicely configured (the way my example 
pic shows), even that is not necessary.

Yes - that's exactly why. I not only don't know where to put the other end, 
but don't know what its number is until I survey the next intersection 
over. Once this is done, the pseudo-nodes could be replaced by whatever 
scheme is used to represent the range of addresses between them.
