Maybe another new group is a cleaner solution

Good point. Editors became Janitors with even less pretext...

QandAEditors had the power to ad/edit/delete content and i do not think this power is related to starred nodes.
Here we have the right to modify a node at any moment, even after years. I think this is a good feature.

It's something to think about. At the very least, we should be able to tell a poster, "Hey, if you fix your writeup like so, we'll give it a gold star."

Maybe starred nodes stay read only until they have a star on it?

I'm concerned about the potential for abuse. QandAEditors have a much freer hand to improve CatQ's and CatA's for the good of the section. (Heck, the original poster doesn't even retain ownership of the post!) I don't think we want to give anyone that kind of license in the SoPW section, regardless of justification.

gods are so rare nowadays: I'd not charge them of other tasks.

Let's not presume we'll have a problem. We can address the problem if/when it arises.
