There aren't multiple entrances in Catonano's examples.

Shops on the corner of two streets is common across the globe.

Are you suggesting these places have multiple postal addresses?

Having housenumbers for every entrance and potential entrance is extremely common in Italy for example. The usual solution is to add nodes with the street name and housenumber at every such point, plus a node somewhere inside the area for the POI (shop, etc.) with the POI tags and the address they use (e.g. Via Cavour 107, or Via Cavour 103-109, or Via Cavour 103/105/107/109, or even Via Cavour 103;105;107;109).

If you want to explicitly tell which numbers belong to the POI I think it is better to draw an approximate polygon for the POI (i.e. you can see from the polygon which address nodes belong to it) rather than grouping them by a relation, for several reasons:

- easier to verify visually
- adds more information (size, shape, topology)
- easier to modify
- easier to understand
- requires less advanced editing tools
- likely more stable because of the previous points
