Depends upon your point of view and boils down to semantics.
The patch doesn't fix any bug or anything like that. It's restoring the behaviour that everyone is used to. It "corrects" how the user set up their template to ignore what docker now calls an error (fatal), by skipping over the offending path. On the other POV, it's hiding the template error by skipping over the offending path.
As @itimpi states, if you don't want this plugin, then don't install it. But, every future release of the OS has this patch included anyways, so it's basically irrelevant anyways.
