I do not understand what workflow you are assuming, so your use
of the word "irrelevant" does not mean much to me.  I suspect
other readers of the patch and documentation wouldn't find it
clear in what situation this option is useful.

Perhaps you are thinking about this scenario?  I am only
guessing because you are not clear enough:

	$ git clone
        ... time passes ...
        $ git checkout -b next origin/next
        ... build, install, have fun ...
	$ git checkout master
        ... time passes ...
        $ git branch
        ... notice that you do not hack on your copy of 'next'
        ... and want to remove it
	$ git remote prune -c

In any case, are you checking irrelevancy?  What if your foo branch has
more changes to be sent upstream?  Even when the remote has a
bit older version doesn't your code remove yours?  For example,
if you did this, instead of the above, what happens?

	$ git clone
        ... time passes ...
        $ git checkout -b next origin/next
        ... build, install, have fun ...
	... find an opportunity to improve ...
        $ edit
        $ git commit ;# on your 'next'.
        ... build, install, test ...
	$ git checkout master
        ... time passes ...
        $ git branch
        ... notice that you do not hack on your copy of 'next' anymore,
        ... and want to remove it
	$ git remote prune -c

If the above is the usage scenario you are trying to help, then
wouldn't it be helpful if you could also help removing 'my-next'
in this slightly altered example?

	$ git clone
        ... time passes ...
        $ git checkout -b my-next origin/next
        ... build, install, have fun ...
	$ git checkout master
        ... time passes ...
        $ git branch
        ... notice that you do not hack on your copy of 'next'
        ... which is 'my-next', and want to remove it
	$ git remote prune -c
