Very good point, I hadn't considered that.
One way (metadata), it's easier to do, but people that don't use it
will be hidden or mixed in.
The other, everyone is equal, but it's harder to do.

Unfortunately I don't think there's much of a solution to this :/

Whilst it's true anyone could use any key/values, I would hope that we
are civilised enough to be able to agree on what keys and values we
use.
I'm a contributor to OSM, and their saying goes:

Simple. if you start using your own key/value, nothing is going to
support it, so you might as well use what everyone else uses.
BUT, as is obvious with OSM, if we don't get the keys/values organised
**from the start**, we will end up with different ways of doing that
same thing and, and I think anyone would agree, that is awful to work
with. If we get keys/values organised at the start though this isn't
really an issue.

Yup, there's not much use to it other than searching, or for linking
documents together (but we already have links to do that, so duh use
them).
Overall it's pretty pointless.
