Allow a node author to easily unsubscribe from notifications

Probably not. This is a very lightweight module. It only stores information about node level subscriptions per user, not per-user-per-node. In order to do this it would have to store the informatio per-user-per-node which quickly becomes a very big database table.

Instead
1) People can create filtering rules in their e-mail clients
2) You could use a more "heavy" subscription tool that provides this feature (like Notify or Subscriptions)

I understand the rationale for closing this in #3 , but this is a really important issue, and the lack of this capability really annoys some node authors.

Comment authors, of course, get an email that lets them unsubscribe easily, with one click. It's the "right thing"

Node authors, on the other hand, get an email that either uses the default language "you're going to get notified forever" or a complicated explanation of how to disable all notifications. It's just not fair :-)

Reopening on tiptoes.

As the title is stated I think this is won't fix. It's the "per-node basis" that makes this won't fix in my mind so I've removed that.

If you wanted to create better messaging and an easy way to toggle the "send me comment notifications for all my nodes" setting I'd welcome that.

edit, removed comment intended for different issue.

It's possible to add a column to the node table to add this setting on a per node basis. This way you don't need a extra table, you just store if you want to notify the author of a node.

Would you accept a patch for this?

Never mind, the Node notify module seems to fix this.

Still a valid and important feature request.
