Yes, for mappers the speedup can be tremendous, in some cities you just have to walk down one street and for every side street you'll immediately see, on the street sign, that this block has house numbers 1200 to 1299 or so. Sometimes the numbering is so regular that this enables you to map house numbers for the next couple blocks down the side street. Consumers will often try to simply dissolve the interpolation line into points which of course has its downsides in schemes like this where 100 interpolated house numbers are assigned but only 10 houses might exist. (I wonder if we need an interpolation type of "sporadic" for that ;) Surprisingly, I have occasionally been asked by paying customers to produce shape files where each street segment has the attributes "house number left from", "house number left to", "house number right from", "house number right to" - which is of course less precision than usually offered by OSM's individual house numbering, but this seems to be a format commonly used by providers of proprietary data and hence there's software that expects that format.
