[Tagging] Is there a way to make tags better?

What about using an existing solution, Wikibase[1] (of which Wikidata is an
example)? Let's call it OSMdata. Wikibase is great because it allows for
all kinds of structured data, which makes it future-proof. Some examples of
use would be:

We could add links to outside databases, for example Wikidata, or some
other structured source that would add semantic meaning to some specialized
tags. So if there is an unique ID of a special type of buoy, connect it to
our seamark:type=cardinal_buoy tag on OSMdata.

Create items that are tag combinations, and give those combinations
additional data. For example, create an OSMdata item for
amenity=place_of_worship+religion=buddhist, link it with the Wikipedia
article about Buddhist temples. This gives more info about tag
combinations, and in some way formalizes those combinations.

Translations to all possible tag combinations (usable by all editors, and
Nominatim for example)

Add additional "meta tags", depending on the region they are found in. For
example, default max_speed on highway=motorway in Spain.

Create items for big geographical entities, like continents and oceans, and
then, instead of relations, tag boundaries of those objects with the
OSMdata ID.

And countless other examples...
