you can't show housenumbers in low zoom levels anyway.

the data is not only for rendering but also for other purposes. If you map
addresses as a point you will have to duplicate this address information on
all contained POIs and features, and you will not know about the extension
of the address (because you never know if addresses are mapped completely).

yes, if the address is not valid for the whole building you will have to
map the address to a different polygon, but this doesn't imply that mapping
it on a node is better. On the other hand if the address is describing an
entrance / a door it should be mapped on this entity (i.e. a point / line).
It all depends where the address is refering to in your surroundings.
