the cryptoloop is insecure, most of the encryption modes are deprecated
(and known to be problematic); util-linux no longer support cryptoloop
options in losetup.

Isn't the better way to go just to remove cryptoloop completely?

I'm not sure if we're going to break existing users.  So maybe for now
get rid of the horrible registration interface, an add a patch to
deprecate it with a warning when people actually use it, and then
eventually remove it. 

Yes, I know that removal is far disturbing thing here, if it
can be planned for removal later, I think it is the best thing to do...

And I would like to know actually if there are existing users
(and how and why they are using this interface - it cannot be configured
through losetup for years IIRC).

Thanks,
