we do have permanent ids for nodes, ways and relations. ;-)
What kind of permanent ids do you want? For some more abstract concept like a road with a specific name? A shop? A building? If there’s a way tagged with building=supermarket, shop=supermarket, name=Foo, and you add a permanent id to it. Then the supermarket gets bought by someone else and changes to name=Pango? Or the supermarket closes. Or it gets torn down and rebuilt by the same operator. Or someone detaches the shop tags and adds them to a node inside.
What happens with the id?

You can have this with relations, but it (associated street, street) did not find a lot of support from the contributors and most mappers have decided for themselves that it does not work for them.
