Tomasz-
There seem to be consensus to apply that.
A consensus of one, I presume.
Warning to certain people: some Polish Wikipedians
want to change default
skin too, and there's nothing non-Polish Wikipedians can do to stop it,
would consensus on it emerge among Polish Wikipedians.
If the project leadership decides that Wikipedias are not allowed to
change their default skin, they are not allowed to do that, and any change
to that effect will be reverted. If, however, the project leadership
approves of giving each wiki the right to change the default skin, this is
indeed a choice you can make.
