Reading about what it is, it is just a lookup between some random three
words and a location. We don't map addr:latlon=51.34,3.45 in OSM, why
would we map addr:w3w? Especially since it is just a lookup. The way I
see it, this is something you would add to nominatim.
I also don't understand this:
"It's a non-hierarchical system. The problem with latitude and
longitude coordinates is that if you make a mistake when writing them
down you will be completely lost. But with our system similar sounding
words are located very far apart so people don't get lost if you hear
it wrong."
First, making a mistake in a lat/lon coordinate does not by definition
mean you are completely lost. It is when you make a mistake in
significant digits (add one degree to the latitude and you're way off)
but it isn't when you make a mistake in the non-significant digits (the
difference between 51.3456247 and 51.3456248 is mere centimeters).
Secondly, if you write a similar sounding word wrong, you are completely
off. I mean, they specificaly say "similar sounding words are located
very far apart".
So if someone tells you nice.place.here and you use nice.place.hear, you
are by definition not near your intended location.
So it seems to me it is already flawed in concept.

Surely the established addressing systems are also closed and
proprietary, in the sense that some organisation with a sanctioned
monopoly tells YOU what your address is - you cannot just make it up
yourself. Street naming, postal codes etc are definitely in this
category. We have been crowdsourcing postcodes for years without
problems.
Integration with nominatim for example, which will need to use the w3w
API, is a different subject as this would need licensing.

Could/should we be doing anything to support/facilitate/implement

No. Other people might talk about the numerous problems how
what3words doesn't do what it claims to accomplish or flaws in the
technical implementation, but there's a much simpler reason why it
doesn't belong on osm.org: It's a closed proprietary system that
others can't reuse.
