Advantage would not only be a simpler code, but also to formalize the
deprecation process a bit, especially for cases where we most likely
will continue deprecate stuff (like old, versioned machine types) in
the future.  It would make it easier to grep for deprecated code.  And
optionally we could put some meta info into the source code, such as
planned removal date and removal reason, which could be printed
together with the deprecation message.

cheers,
