Short description of the issue

I'm cleaning up my forms module and have a page structure like this:

As you can see there is a "move" action for every saved form entry. The thing is... It is not allowed to sort/move these pages:

Expected behavior

Wouldn't it be nice to not show the move action at all if the family setting prevents manual sorting? I guess it's not as easy as in my example, right? Because one could also want to move the page to another parent, which could actually be allowed. Not sure how to tackle this - has there been any discussion about that? I couldn't find anything.

Workaround

As I'm hiding these pages in the pagetree and only showing them in a custom process module I came up with this workaround:

.PageListTemplate_rockforms_entry .PageListActionLock,
.PageListTemplate_rockforms_entry .PageListActionMove {
  display: none !important;
}

If there is already a way to solve this properly please let me know, thx! :)
