Other address imports (like the one in Denmark [5]) also only used simple nodes.

I agree, lets keep/fill the tags. Nowadays i think that space is not really a problem, if we could have as much data as possible it is sometimes easier to extract the data without fiddling with relations etc. (KISS).

Except of course, when OSM is incorrect (e.g. if the position is far off, or a house with multiple numbers has only one in OSM like in your example, etc.). In that case it would be OK to delete the data and insert more precise addresses instead.

This is because the POI can relocate or disappear quite quickly, while the actual address usually doesn't.

Should it not be also apropriate, to tag the imported data with some unique source:* tag that the data could be updated from time to time ?

my 2¢

ps: is there some public "opendata" access to the WEGE db ?
