Yes, that's what I have in mind.
Tagging with "addr:housenumber=5000-5310, addr:interpolation=yes" might be
a good idea for the cases when otherwise the length of concatenated value
of "
addr:housenumber=5000; ...; 5310" is longer than 255 symbols. But maybe we
should not reach even that length and adopt a rule of using interpolation
if the length of addr:housenumber becomes larger than, say, 10 or 20
symbols?.. Otherwise the long strings of housenumbers will make the map
harder to read.
