In principle you should be able to select every vald in Estonia. They've
got a relation of admin_level=8 around them. Maybe this relation also
needs to be made up of only ways with admin_level=8.

We currently have some borders that have odd intersections (mainly found
and fixed them on the coastlines so far).

Those issues look something like this (exageration):

                 |
                 | A
                 |
                 +
                / \
             B /   \ C
              /     \
        -----+-------+-----
          D      E      F

Then we have relations:
admin_level=8: D, E, F
admin_level=9/1: A, B, D
admin_level=9/2: A, C, F
And of course there are even more weird versions of it.

If now someone tries to correct that, he might remove E and join D+B and
C+F ... potentially leading to incorrectly tagged admin_level.

Additionally some JOSM versions had a problem with joining two members
of the same relation ... by default (and anything else being virtually
invisible initially) this produced duplicate relation membership. [At
least I know, I produced some of those issues].

Well, I'd rather leave the centroid where it is. And maybe add it to the
relation ... I've seen it somewhere ... or was it for the capital?

Additionally you never know who might need it. But let's see what'll be
the result.
