yes, just one hint:  --poi-address is the default

The formatting is done by the Garmin software, not by mkgmap.
It just fills individual fields and we have a few flags for the whole
tile to say how to format them. These flags are configured
in resources/LocatorConfig.xml , e.g. Island (and Germany)
have streetBeforeHousenumber="true" postalcodeBeforeCity="true"

Well, the current code for the --housenumbers option will treat a
housenumber like "3/5/3" like "3", so I think you can do that in the
style.
