Better late than never, though the patches are already in master branch
and I am horribly late.

I don't like to see this very specific command in the first level of
command namespace. In the past we've proposed a group named 'rescue'
that would collect functions that are potentially dangerous but perform
certain tasks that can make a filesystem usable again.

Examples are select-super or zero-log that are now separate utilities.

As a related topic, I was thinking about intorducing a separate
namespace that would be declared unstable and any feature in development
would be free to use it and add/modify/delete commands and params as
needed. That way developers can focus on the feature itself and let the
user interface polishing for later.

And now the name of the namespace: how about _ ? It's short, will never
clash with any other command.
