I've noticed the appalling trend to apply restrictions to content improvement on talk pages. Wide ranging discussions on talk pages are important to the better understanding of many articles.
It varies. In the case of low controversy or just plain obscure stuff it may be helpful. In the case of articles like [[Barack Obama]] or [[Loose Change (film)]] it is unlikely to be.
In practice this is how it tends to be.
