I've fixed a lot of those when going through
The rule I personally applied was: leave the wikipedia tag if there is a
significant amount of information on the page it redirects to. What
constitutes a significant amount is a bit of a gray area. If there is
a dedicated subsection, then that is clearly significant (and I prefer
the redirect over linking to the subsection of a page). There are
wiki pages that have the entire history of a group of villages. That may
be significant for each village. Just the mention that A is a subpart of B is
definitely not significant.
So in the particular case of Hurnen, I'd lean towards deleting the
wikipedia tag, too.
But that's not necessarily the general rule. So it's probably worth
asking for an opinion on redirects in that case from the wider community.

I've been fixing a lot of bad wikidata from this import. Note that Yurik did
these edits not only in Switzerland but worldwide. Still, I think that the ship
has sailed. A revert would be a bad idea now. Rather create a MapRoulette
challange of suspicious tags from that import, so that a human can look
at them and fix them.
