There are no deprecated tags, and nobody has the power to "set a tag to 
deprecated".

What's even more problematic is if people try to automatically change a 
large number of objects away from what they consider "deprecated" to 
some "new tagging scheme". This requires a much broader approval than a 
few votes cast on a wiki page that nobody reads; we expect any automated 
or even mechanical edit to be discussed on the mailing lists beforehand.

This is not true; there are many tags that are not rendered and the map 
on www.openstreetmap.org is not the arbiter of what tags should be used.

Yes, this is not helpful, and certainly no basis for effecting an 
automated edit.

When looking at the other edits of the user who did this edit, we can 
see that not only did they make this tag change across a number of 
changesets; they also imported wind turbine data from a third-party source.

Unless they can point to a community discussion and agreement that 
preceded the import, they should not only revert their mass edit, but 
also remove the imported data because it doesn't meet our import guidelines.

Morten, could you keep us posted about any replies you get from them. It 
would be preferable if the Netherlands community could deal with this 
but DWG will be happy to step in if there's a problem.

Bye
